I have a longstanding installation of SOGo that was reasonably stable
until recently. I stared experiencing intermittent instability such as:
* Any UI action (e.g., select email message) would hang.
* Login would succeed but I would be greeted with a blank screen.
I updated to 5.12.4 and did a bunch of changes (basically
increased WOWorkersCount), but the application seems to be suffering
from resource exhaustion.
I started seeing a bunch of:
sogod [217867]: [ERROR] <0x0x55980c462e60[WOWatchDog]> No child
available to handle incoming request!
I edited /etc/default/sogo and changed PREFORK to 10, then to 20.
I changed /etc/memcached.conf and increased the memory ceiling from 64
MB to 512MB.
In htop, the memory usage is pegged at 5GB of 16GB total, so it does not
seem to be server memory limitation.
Other log entries that may or may not be relevant:
sogod [301075]: [ERROR] <0x0x7f4346b543e0[GCSAdminFolder]> 'OCSAdminURL'
is not set
I edited sogo.conf and included this setting, so this is probably
fixed by now
sogod [303128]: <0x55c1aa8257d0[SOGoMailAccount]:0> renewing imap4 password
I see a bunch of these, not clear to me if this is an issue.
sogod [303126]: [WARN] <0x0x7ff7cc52ebe0[WOxElemBuilder]> could not
locate builders: WOxExtElemBuilder,WOxExtElemBuilder
sogod [303118]: [WARN] <0x0x55c1a9f7cbc0[WOWatchDogChild]> pid 303139
has been hanging in the same request for 1 minutes
I see a lot of these warnings, and I imagine that they relate to No
child available to handle incoming request!
If anyone has any troubleshooting suggestion, please let me know.
Thanks,
Andrei Goldchleger
