78.13.0 crashed on me today with an out of memory error, which I've never seen before. The suggested RAM for the system is listed as 512MB. The system has 4G and 'free' said just a little over 1G was being used at the time. The system is stable and still running:
Code:
$ free -h
total used free shared buff/cache available
Mem: 3.8Gi 701Mi 1.2Gi 8.0Mi 1.9Gi 2.9Gi
Swap: 4.1Gi 0B 4.1Gi
I run thunderbird on a 20.04 system inside a firejail with memory constraints (3.7G limit), using X11 forwarded through an ssh connection to an 18.04 server with a lite-window manager, fvwm. It refused to startup with a 3.5G RAM limit. After the OOM error, I bumped the RAM limit to 4.7G and restarted. Here's the process table entry:
Code:
tf 357708 357700 0 09:52 ? 00:00:00 /usr/bin/firejail --dns=172.22.22.80 --rlimit-as=4700000000 /usr/bin/thunderbird -no-remote
Only posting because it happened just a few minutes before I saw this thread. May or may not be related. I only have the Canonical repo version of thunderbird.
On another system here, 18.04, I run TB locally and haven't seen the same issue - or any others recently. It also runs inside a memory constrained firejail.
Code:
tf 4265 4264 0 07:50 ? 00:00:00 /usr/bin/firejail --dns=172.22.22.80 --rlimit-as=3700000000 /usr/bin/thunderbird -no-remote
rlimit is just a limit on virtual memory.
