Thunderbird Excessive Memory Use - Over 3GB
My TB 147.0.2 Release channel is using excessive amounts of memory. Below is the memory usage data.
Previously I was on the ESR channel for many years. Also I originally used the Lightning calendar plug.
What I'm seeing is that when TB starts the memory usage is high. If I check at another time on the same day it is sometimes only around 250-350MB.
I've tried suggest options like reducing data in Local Folders (on a separate data drive) but to no avail. As I type now TB memory usage is now only 286.4MB. However rest assured in a while this will jump back to over 3GB and it has an is now 3,151.4MB.
I don't see this on another 2 PCs. One is setup with Locals Folders and the other is just the mail Inbox and sub folders. The only other difference is that the PC with this TB installation also has one Newsgroup server configured.
There surely has to be a bug somewhere causing these excessive memory usages.

Thanks for the memory "map". Unfortunately it tends to be unhelpful, because we can't see what service or task is generating the memory usage. Also, folder related storage (which I don't see there) tends to be wildly inaccurate.
High memory can come from corrupt folders, add-ons, and many other things - but not so much from "good" even extremely large folders. So reducing data isn't going to be helpful.
Quick items:
- Try Help > Troubleshoot Mode.
- Do you have any folders where you've seen problems?
- Do you have many newsgroup or rss accounts, or virtual folders?
For a longer list, see https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems
Let us know what you find.
Well that is a long list of things to check :) Thanks for replying
I can rule of most of those listed item already.
1. Yes latest 2. Troubleshoot - Disabled All Addons - no effect - straight to over 3GB usage 3. NEED TO DO, but I think I've tried this before 4. Not seen anything 5. No proxy defined 6. No effect - straight to over 3GB usage 7. No Gmail - N/A 8. Can not find that 'unified folder' mode / setting - Where Is It? 9. Nothing shown about folders in Help Troubleshoot - Where is it? 10. No remote calendars 11. No effect - straight to over 3GB usage 12. No effect - straight to over 3GB usage 13. No effect - straight to over 3GB usage 14. Windows search/indexing/integration not set 15. Low % usage - <1% but still over 3GB 16. No effect - straight to over 3GB usage 17. No remote or external disk profile - profile on C: drive 18. No high or slow disk activity 19. Nothing shown / happening 20. All OK 21. THIS WILL KEEP ME BUSY 22. MIGHT END UP HERE
Will follow-up
OK I've found the problem.
After trying all the other items mentioned before doing a totally fresh reinstall of TB with new profile etc. I decided to delete the news server account (news.grc.com). Bingo, problem solved.
I've been running and testing all day and TB memory usage has not gone above 220MB.
Clearly there is something wrong with TB's news reader code.
As my other machines also had no news server accounts and they did not have the high memory usage problem I' happy 3:1 that it is a TB problem.
It would be interesting to know the file sizes.
Do you still have a backup or copy of the news account files?
Which newsgroups of that news servier are subscribed?
Hi Wayne
Sorry for the tardy replay.
I no longer have the files to be able to say how big etc. they were. I can say though that they were not massive and I regularly deleted any downloaded threads.
As for number of groups basically all on the server less about 5, making 32. Quite small compared to many usenet servers. All all text content as well.
You can try for yourself. news.grc.com is GRC's public server which anybody can subscribe to.
There is a Test group.
If you want to post or delete then you need to set a Cecil-ID
You need to create a Cecil-ID.
1. Set the server address (host name) to "news.grc.com". 2. Set the port number to 119 (should be default) and disable any option to use a secure connection. <== CHECK THIS
You then need a CECIL-ID to post and cancel messages:
3. Set the login method to "Username and Password" and enter identical strings into the Username and Password fields to serve as your CECIL-ID. Pick something unique and stick with it as the first 29 characters becomes your server identity. 4. Set your posting Name to whatever you'd like to use.
Remaining non-critical steps would include:
5. Set your E-Mail address to some string. Many people enter a fake e-mail address here, such as "yourname@email.invalid" 6. Optional: Enter or Add a "Reply-To" field containing a real e-mail address, if you wish.
You must log in to your account to reply to posts. Please start a new question, if you do not have an account yet.
