I have been a happy user of Thunderbird for >>10 years, and it has been solid most of the time. But now, it suddenly has been in a mode of constantly "Not Responding". It will be completely non-responsive for maybe 30 minutes, and then partially recover until I do something else, using about 18% of CPU and < 500MB memory. At this point, it is essentially not functional, but it is not crashing completely.
Sometimes I get message that the mail host did not respond to DELE command or that the mail host is not responding due to timeout. I figure this is just because it has reached the max timeout.
I have installed the latest version of Thunderbird, (102.1.0), deleted all the .msf files and went to each folder and rebuilt it. Real-time virus protection turned off for testing. This is running on Windows 10. This sort of started after the recent Windows 10 update, so perhaps other people are encountering this. I did not see this exact same problem.
Sometimes it hangs really badly and provides a little tiny image of the window, about 1/2" tall and 2" wide. Then I have to kill the process. I attached a typical process summary when this is hung. It is completely not responsive for many minutes each time. I don't get an error message every time. It definitely hangs if I check for mail from the server, or sometimes try to delete a message. Here, I started Thunderbird in safe mode, with no plugins, and with real-time virus scanning disabled.
Attempted to get email, It hung (Not Responding) After 30 minutes, received this message:
Sending of password for user ____ did not succeed. Mail server mail.XXXXX.com responded: Disconnected for inactivity during authentication.
Login to mail.XXXXXXX.com failed with username ____ failed. (retry, enter new password, cancel) Entered password. Then it accepted password.
Downloading message NNN of 1078
Proceeded without problem to message 198 of 1078
Then, "Login to server mail.XXXXX.com with username ____ failed. (retry, enter new password, cancel) Hourglass... can't enter new password. Started hourglass at 10:06am.
10 minutes later: "The DELE command did not succeed. Error marking a message as deleted. Mail server responded: Disconnected for inactivity."
was able to delete messages in the Inbox and to reply to one email.
Selected mailbox "WhiteBulkBox" Hung again, starting at 10:48am Process display looks similar to the clip attached. recovered at 11:04am Selected folder properties, then Repair Folder. Hourglass. not responding. 11:43 Recovered. Random request for password popped up. WhiteBulkBox should be repaired. Clicked "Repair Folder" again. There are only 501 messages in the folder. 504MB size. Hourglass at 11:45. Same process listing. 12:24 noticed it had recovered. Clicked ok without re-repairing the folder. Clicked on first item in the folder. Hourglass. 12:25pm Same process listing. 21 to 37% CPU Gave up at 2pm. Killed the process. restarted in troubleshoot mode, 2:01 pm. Hourglass. Recovered by 2:40. opened Inbox of one email. Hourglass at 2:44 3.24pm was able to delete several files form Inbox. Now it is empty. Properties, repair folder. Hourglass. Crazy that it would have such trouble repairing an empty folder. recovered at 4:07pm. Now show 0 messages in Inbox, but size on disk is still 87.8MB. That seems sort of strange. Clicked "Repair Folder" again. Finished quickly. There was one message in the folder, marked ***SPAM***. This is strange because I had turned off automatic checking for new messages. Hourglass started at 4:11 pm 4:35pm recovered. Checked server settings, all set to not automatically check for new messages, did not make any further changes. Selected inbox of one user, Repaired Folder, finished quickly. But then went into hourglass mode. 4:37pm 4:57 recovered. Clicked on folder "WhiteInBox", clicked "Repair Folder" no hangup. Back to WhiteBulkBox. Clicked it, Not responding. 5:00pm 5:20pm recovered. This WhiteBulkBox seems to be a key problem, and may be the reason getting new mail fails. Right-clicked the folder, Properties, Repair Folder, hourglass. 5:22pm 6:16pm recovered. clicked OK Now try to delete messages in WhiteBulkBox. clicked first message, message displayed. no problem at first. press DEL key, hourglass. 6:17pm still hung, 7:30pm. I think like the last time, this will not recover, but I will let it run to see. Meanwhile, I will submit this information and hopefully someone might have a similar experience. Please help! Otherwise, I will have to abandon Thunderbird.
