Thunderbird froze my BlackBird while "Compacting'

[cchinicz]

Hi All,

I'm using this Black Bird for two weeks now. I've installed Fedora 32 with KDE/Plasma on this Power9 v2 machine with 32GB, 4 cores and plenty of disk.

When compacting the local mailboxes (Thunderbirds asks for it a few times a day) usually Thunderbird becomes unresponsive but I can use other applications. Today it froze the whole system for about a minute, I could not change application, it made remember Windows 3.1 with it's incipient multi-tasking capability.

My system barely gets over 40% memory util and vCPUs were supposed to work independently one from the others.

Any ideas of what might have happened? I wonder may be disk access. I have two disks: 128GB with boot and LVM for root/local. The second disk of 256GB I use a partition of 120GB as a LV which I added to LVM and used it full to extend /home. Both are PCI connected.

Maybe when compacting the mailboxes the access to the disk made by Thunderbird are so heavy to the point of not allowing the system anything?

Any inputs are appreciated.

Regards

What type of disks? NVMe, SATA over PCI, ?

Never seen anything like that with F32 on my system, but I read mail on spool as G-d intended.

Hi,

Both are NVMe over PCI. I use Thunderbird because I work with gmail and I cannot stand it's web interface, just cannot find things at a glance like with Thunderbird.

I have changed the settings, so the "compress" message doesn't popup again.

Hi,

Thanks for the information, I found it where to clear the "compress" option.

Does anything interesting appear in dmesg after?

[cchinicz]

Hi I have no idea of what dmsg is. How do I check it?

Open a terminal window and type 'dmesg'. A lot of output may appear; you're interested in what's down near the bottom, particularly anything obvious that might say BUG: (a kernel issue) or a crash dump.
