Is it crashing? Then please post a crash ID. https://support.mozilla.org/kb/mozilla-crash-reporter-tb#w_viewing-crash-reports

Or is it not responding?

Christ1,

TB crashes after 20-30 seconds. Also, I have seen that the crash reports have been submitted. What do I need to do now?

Post here the unique case number of the crash report so someone can look it up in the relevant database.

Zenos,

The ID is given below.

Hi Zenos,

Any advice please?

I am no expert, but the crash report links to malloc and garbage collection tasks. This is the last function called, which raises the exception:

mozalloc_abort(const char* const msg)

and it appears to be failing because it cannot allocate memory; often this means it has all been used up.

This is a bug (though it is Mozilla code, not specific to Thunderbird) and shouldn't cause a crash, though running out of memory is a difficult thing to handle well.

Having said that, you say it has got to 7000 - 8000 messages, implying there are yet more to process. I don't think you're doing yourself any favours by allowing messages to accumulate to such large numbers. I can't begin to imagine how you can usefully work with such a large pile of messages; I file mine into subfolders by topic or context.

I don't know how you back out of this. You could remove the offending folder from the profile as a quick and dirty way of getting Thunderbird working again, but of course that means you can't see your store of older messages.

lsingh, has your crashing stopped in version 52.1.1??

Wayne,

Yes it has, but I had to remove all the archive folders in the Local Folders, and then put all the files back in slowly. Took a few days to do it.
