I've recently setup a munin-node on a CentOS server. All was working fine until I tried to add the apache plugin (which works fine).
For some odd reason, the mysql plugins for munin that used to work ceased to work... I'm now getting a weird error whenever I'm running the plugin with munin-run. For instance
IPC::ShareLite store() error: Identifier removed at /usr/lib/perl5/vendor_perl/5.8.8/Cache/SharedMemoryBackend.pm line 156
but sometimes it will also return
but after a while it will revert to the previous error.
I do not have any knowledge about the IPC or the ShareLite library so I don't really know were to start looking. Since it is a module related to shared memory, I tried tracking down shared memory segments with ipcs without much success.
I haven't yet rebooted the machine as it is used for many projects (I'd obviously like to be able to diagnose the problem without requiring a restart if it was possible).
Has anyone faced this problem? (a quick search on google didn't present any relevant help)
Thanks for the help!
