1675407 - Installed TB 78 and now TB uses 100% CPU and increasing memory until "not responding"

Status: RESOLVED DUPLICATE of bug 1662759

(Thunderbird :: OS Integration, defect)

Description

[blixio]

Attachment: thunderbird 78 force quit report.txt

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.1.2 Safari/605.1.15

Steps to reproduce:

Install TB 78.4.0 on iMac (Retina 5K, 27-inch, Late 2015) running 10.14.6 with 8GB memory (update from TB 68.8). Run TB.

Actual results:

When started it runs for a while and is able to get mail but soon is consuming 100% CPU time and an ever increasing amount of memory. When it gets to almost 8GB memory TB stops responding as reported by Activity Monitor and Force Quit.

Expected results:

It would have continued to respond and not consumed all CPU and memory.

Start macos in safe mode https://support.apple.com/guide/mac-help/start-up-your-mac-in-safe-mode-mh21245/mac

Still In Windows safe mode, start thunderbird in safe mode

No clear items stand out.
Current list open performance bugs is https://mzl.la/36iYMbc (from query https://mzl.la/3eGhVaT )

Increasing memory tends to come from corrupt folders.
But an alternative from that list is bug 1662759

Thanks Wayne
I’d given up on Thunderbird and started using Bluemail (but hated it). Your post prompted me to look again at bug 1662759. I missed the bit about changing ldap_2.servers.osx.dirType to "-1" but I disabled Thunderbird access to the system address book as suggested in later comments (eg 24 and 25) by going to System Preferences>Security & Privacy>Privacy>Contacts and unticked Thunderbird. I eventually checked ldap_2.servers.osx.dirType in the profile file and it was set to "-1". I guess because I'd unticked Thunderbird. Thunderbird seems OK now so I'll have to check that I haven't lost emails downloaded with Bluemail.
thanks again
I think your prompt did the trick.
