Hi,
sorry to hear the crashes don't go away.
I didn't have a look at the information you provided yet, so I can't
really provide help now.
Regardng RAM/swap upgrade: You seem to run a 32 Bit kernel with no PAE
feature enabled - would adding more RAM/swap really help ? ;)
How long is Icinga2 running until it crashes? Can you trigger the crash?
I'd strace the current process until it crashes and have a look at the
output.
Best,
Valentin

Hi.
Does anyone have any further ideas on what can be causing this, or how I can
get more information about how to fix it?
I'm still getting crashes with the error message shown in the subject line.
Sometimes they occur within a few minutes of the previous one; or the system
can keep going for several hours without a problem.
Any ideas are most welcome.
(Oh, and by the way, the suggestion of adding some swap space, despite the
machine already having 4Gbytes RAM and only using 10% of it, turns out not to
be possible, because the hosting provider doesn't allow swap to be turned
on...)
Thanks,
Antony.

Alternately: run 'sar -r 10' (sar is in the sysstat package, -r
reports on memory usage) capturing the output to a file. If you see
committed memory (%commit) usage growing towards 100%, and then
freeing up after icinga dies then you have a reasonable diagnosis.
I'll log to a file and wait...
Crash report attached - time of failure 13:42:11
sar report from 13:30 onwards also attached.
I see no indication of all 4Gbytes getting used up.
The only thing I would mention is that this crash occurred 1 minute 6
seconds after I performed an "icinga2 reload" on the master server.
However, the crash I got last night, timed at 00:02:33 was ~20 minutes
after the previous reload (23:43:10 - I have timestamps on my bash
history).
Any further ideas please, people?
Antony.
