Hi.
I've been using Icinga2 for several months now, and I've got quite a few
servers configured in a hierarchy.
This week I've just added a new machine for monitoring a customer's network,
and Icinga keeps on falling over saying "cannot allocate memory".
The machine is a Virtual Server with 4Gbytes of RAM, and at the time icinga
falls over, "free" tells me:
Mem: 4194304
Used: 345328
Free: 3848976
So, I certainly do not believe Icinga has run out of RAM.
The machine is an identical specification VM to one that I've been using since
October 22nd as my Master instance, with all the configuration files on it.
Icinga2 has been running perfectly happily on that since I set it up.
Both machines are running Debian 7 "wheezy", 32 bit, and I've installed
Icinga2 from the debmon repository.
Version: 2.6.3-1~debmon70+1
The server with the problem is running a few standard "local" checks on
itself, and is also running 13 plugin checks over SSH to 18 other servers
(which I think is not a big workload...)
When Icinga shuts down claiming it can't allocate memory, it generates two
reports in /var/log/icinga2/crash; I've attached the latest examples of these
for info. The same sort of thing also goes into /var/log/icinga2/icinga2.log
Googling for the error message, I've found https://dev.icinga.com/issues/10655
and https://dev.icinga.com/issues/10839 however those seem to indicate that
the problem was fixed in Icinga 2.4.2?
Is there any further information I can provide to help pin down what's going
on here?
Can anyone suggest how to fix the problem? It seems strange that I have it on
one machine but not another, both identical spec, identical O/S install, and
identical Icinga2 versions...
Thanks,
Antony.
