How to reproduce: 1. Generate a folder like below with Explorer C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\Profiles\<Profile name>\Mail\Local Folders\foo\cur 2. Put many emails into the generated folder in Maildir format 3. Run Thunderbird 4. Select the folder to generate MSF file 5. Thunderbird crashed after several minutes Sometimes 1200 emails are OK, and at other time 1000 email are NG. So it depends on the condition.

3 of the 4 are OOM | small. #3 Either there is a bad memory leak? (not closing files?) Or foul play. Please start *Windows'* safe mode with networking enabled - win7 https://support.microsoft.com/en-us/help/17419/windows-7-advanced-startup-options-safe-mode#start-computer-safe-mode=windows-7 Still In Windows safe mode, start thunderbird in safe mode - https://support.mozilla.org/kb/safe-mode-thunderbird Does problem go away?
I cannot change boot option because my machine using Thunderbird Nightly is not under my control for that setting. In case that folders "foo" and "bar" which have >1000 emails each (and MSF files are successfully generated), moving all emails from one folder to another is no problem.
You must have a very strong interest in maildir. You have several major extentions installed. At least please try starting Thunderbird in safe mode. Please also use the current nightly 54.0a1. Thanks Oh, and why are they making you run win7 in 32bit? That's pretty horrible.

> 2. Put many emails into the generated folder in Maildir format Note - I'm not sure this is expected to work.

Do you also see this problem if you use the beta from http://www.mozilla.org/thunderbird/channel/ ?
I checked the issue still occurred or not with Thunderbird 60.0a1 (20180219030201). And then I got OOM | small crash. b693e37d-9950-4a70-a4a0-33eb60180220
I checked with suggested beta build and the problem is still present. :(
I have the same problem - is there any way to repair/ build msf file without thunderbird crashing in the process??
(In reply to skrytka from comment #12) > I have the same problem - is there any way to repair/ build msf file without > thunderbird crashing in the process?? p.s. i have 32 GB ddr4 3200 RAM and maildir folder is on NVME SSD drive. I can't build msf file. I lost all of my emails
I have folder with mails (1 year, 70 000 mails) Now I copy 800-900 files to a temporary folder, repair the folder, transfer all the letters to the desired folder. If I have more than 1000 mails in folder - I got crash. But even if I have 900 mails sometimes I have situation than TB moves 800 mails, and remain still 100-120. They can not be migrated before the program is restarted. I'll continue copying for now, if I notice some other regularities then I'll write here.
