The program essentially crashes midway through the process. If multiple messages are moved, some of them are copied to the new folder, but not deleted in the originating folder, and so duplicates are created. The behaviour is worse on slower internet connections. Reproducible: Sometimes Steps to Reproduce: 1.select a large message in message list (or select a large number of smaller messages) 2. type "A" for archive, or drag and drop to another folder 3. Thunderbird begins the copy process 4. Copy never finishes (large message is not copied, or the list is only partially copied) 5. delete of messages in originating folder never happens, so some messages are now in both folders. 6. Thunderbird becomes unresponsive, needs to be force-closed. Actual Results: 1) TB crashes 2) sometimes some of the messages are copied, but not deleted from the source folder, so there are now two copies of these. There is no easy way to tell which messages were duplicated. Expected Results: Messages should be moved without a crash. The move process should take into account the potential for network dropout or other interruption, and not duplicate messages. This means moving them one at a time, not doing a two step process involving a bulk copy then bulk delete. Might be similar to: https://bugzilla.mozilla.org/show_bug.cgi?id=583365
I looks combination of next phenomena. (1) Huge momery use by bulk move of IMAP folder due to bug 538378, then slowness like bug 583365 comment #1 happened by swap file expansion of OS. Unresposiveness of Tb occurs too in such stuation. (2) You killed Tb in such situation, then crash like bug 583365 comment #0 occurred(killed by OS in that case, because swap file can't be expanded) (3) As you say, "bulk move" is roughly "bulk copy"+"bulk delete(store flag \Deleted)". As you killed Tb during "bulk copy" phase, "bulk delete" phase was not executed. Can you observe crash without killing of Tb?
Actually it always locks up. In Win7 the main app window and all open compose windows freeze and become unresponsive. Clicking on them prompts the windows kill dialog. Checking the task manager shows either sustained 100% CPU, or 0% CPU -- I see either on occasion. I usually wait for several minutes to let it finish its thing, but it never comes back. If I leave TB running overnight, it is in an identical state when I check in the morning -- unresponsive, and sustained 100% or 0% CPU. If I check my IMAP folders online, no changes are made from the moment of the lock up.
I should add, I regularly receive email attachments between 1MB and 20MB, so I see this type of lock up daily.
(In reply to comment #2) Problem itself with IMAP is dup of bug 538378. "bulk move of IMAP" looks to produce critical problem than "bulk move of local folder". If auto-sync is enabled for move target folder and IDLE is enabled, download by auto-sync can be initiated during the "bulk move". If Gloda is enabled, indexing after download may be initiated. They make situation worse. (In reply to comment #3) > I should add, I regularly receive email attachments between 1MB and 20MB, so I > see this type of lock up daily. I think mail size itself is basically irrelevant to problem and "number of mails" is key factor, although mail size can affect on required memory size if "viewing of moved mail" is involved. How many mails do you move by one operation regularly? How long does the "daily move" take? What is Virtual Memory Size and Real Memory Size used by Tb while the daily bulk move is executed(and Tb is unresponsive)? No swap file expanding by OS during the daily bulk move? bug 538378 is probably mainly for huge memory usage while "UID COPY ... target" and "UID STORE ... flag \Deleted". What is your IMAP delete model? Do you enable option like "expunge after each delete"? Is deep thread and/or long thread is involved in you daily bulk move? If auto-expunge is scheduled and deep/long thread is relevant, bug 452221 also can occur after "UID COPY ... target" and "UID STORE ... flag \Deleted" and EXPUNGE.
Hi all, I'm a sysadmin for several small enterprise environments. We have massive problems with this known bug of Thunderbird. In order to keep actual system configuration I am seeking help of a professional. Is there at least any workaround, if the real cause itsself cannot be found?? My costumers would even make a donation to get rid of that problems. No other mail client behaves like that. (tested pegasus, emclient, opera, even during the "catastrophies" these behave relatively normal. ...) ################ the problem ####################### One mail-users action trying to archive about 7000 old mails caused about 38000 mail duplicates and the server to hang. This happens similarly almost every week. Restarting dovecot or the hole server doesn't help, in one case restart of apache2 helped a bit, I have no idea why. During this situation every other user sending an email gets a message , that saving to sent-folder failed, asking him to retry, But this is not true, the mail is already in the right place in the sent folder. This causes more and more duplicates and more an more traffic. Some user experience errors while writing mail bodies, that saving to drafts fails , others loose saved drafts. We use Thgunderbird, because there's no alternative mail client supporting imap, caldav & ldap Adressbook (evolution win32 was reported to do so, but doesn't function at all) I've found many listed bugs in bugzilla that in my opinion are caused by one very basic misbehaving of TB. If it does not get answer from the server within a certain time, it like a bull in a china shop it blindly shoots up to 5 times the same transaction to the server, not beeing able to handle any of the servers feedbacks. This seems to be a very old bug , i found at least 3 year old duplicates, with TB 3 ist has become much more severe. ############## the system environment ################### Server: Ubuntu 8.04 lTS with dovecot 1.2 maildir , postfix, openldap, davical, apache2 65 Mail Accounts , up to 25000 mail per user , some of them have mutliple cascading subfolders. all together 200 GB and 600000 mails. 50 Clients winXP Sp3 Thunderbird 3.1.9 with Lightning Several Clients are over 5 years old network: 100Mbit/s , 2 main central switches have 1000 MBit/s ############### some of the bug IDs that sound similar to me ####### This is a lot of stuff , delete it if you like: 492672 nor -- All firstname.lastname@example.org NEW --- Need to adjust IMAP dynamic timeout algorithm to compensate for both slow servers and large emails 583365 cri -- Wind email@example.com NEW --- Memory leak ending in crash when moving 70k emails from inbox to archive (large real memory is required for bulk move/delete of mails, and real memory used by "select+all and move/delete" is not released until new Tb window open and old Tb window close) 476074 maj -- All firstname.lastname@example.org UNCO --- deleting or moving large numbers of messages at once very slow with high cpu usage 482368 nor -- Mac email@example.com UNCO --- Mail deleted from preview pane becomes unread in Trash folder 505443 nor -- Wind firstname.lastname@example.org UNCO --- Deleted messages (two folders only) re-appeared en mass [pop] 519083 nor -- Wind email@example.com UNCO --- message duplicated when copied or moved from filter 537192 cri -- Wind firstname.lastname@example.org UNCO --- Folders moved from Local Folders to Archive disappear, but can still be referred to in the menu MESSAGE>MOVE TO [?] AGAIN, and any use of that menu item causes more messages to disappear (even from the archive) 538591 nor -- Wind email@example.com UNCO --- Copying imap folders to local folders by dragging doesn't copy all of mails in IMAP folder/subfolders 539494 nor -- Wind firstname.lastname@example.org UNCO --- IMAP Cache Should be Stored in "Local Settings" Application Data Folder (IMAP Cache: IMAP offline-store file by offline-use=on, never Disk Cache) 541669 cri -- Wind email@example.com UNCO --- Moving emails creates 1000's of duplicate emails (IMAP)! 545082 maj -- Wind firstname.lastname@example.org UNCO --- Filters filing to IMAP folders not running automatically (quarantine option=on/mailnews.downloadToTempFile=true, "MOVE to IMAP folder" action does nothing) 549405 maj -- Wind email@example.com UNCO --- inconsistent message list when using IMAP and a webmail interface successively 553564 nor -- Mac firstname.lastname@example.org UNCO --- Delete mail button stops working 556232 cri -- Wind email@example.com UNCO --- Cannot move a message from a folder to another one.Sent email (or other emails) can't be copied to sent folder.
