I use Thunderbird with a wireless LAN through a Dlink Router. The router tends to crash when too many connections are opened on the network. I am running a mail server on one of the LAN computers and accessing the mail via IMAP through a wireless router to Thunderbird. The mail server is 'wired' to the router. Thunderbird is Ver 1.06. I recently noticed Thunderbird causing the Router to crash. It only happens when I have a large number of emails in a folder and try to view the folder contents. If I log onto the Mail server with a web browser and move some of the emails to a subdirectory the network remains stable when opening the directory after the mail has been moved. Strangely, Outlook does not cause the network to crash regardless of the amount of mail in the directories. If you can tell me how to log the connections or create some sort of trace file for you I would be glad to help. I have 5 accounts setup to access different mail accounts on the same mail server. This may compound the problem. Reproducible: Always Steps to Reproduce: 1. Get an home router with allowing a maximum of 256 simultaneous connections 2. Run a mail server on network. 3. Use TB to access more than 256 messages in an IMAP folder on the mail server, through the router. Actual Results: if the router is a Dlink, it reboots, the network falls over and TB displays a message that the Mail Server cannot be contacted. Expected Results: Downloaded and displayed all messages
we cache connections to imap folders, up to a limit of five connections per server. You can change this to any number you want in the advanced imap server settings, e.g., 1.
Thanks David. I tried that but it didn't work.
er, you mean it didn't fix your problem. But I think it does cause only one connection to the imap server to be held open. netstat will tell you for sure.
I also have this Problem with Sm 1.0 under Win and Linux. Under Linux netstat shows me multiple connections opened to the IMAP server.
Yes, but did you change the setting for the number of connections we cache to the imap server? (the setting is per-server, so if you have 5 servers, and we cache 1 connection to each, you'll get 5 connections, not 1)
Chris, do you still see the bug?? based on reporter: "I no longer use the Dlink router, and don't experience the drop outs" the could be marked invalid.
original report invalid per reporter
