Restart XCP-RRDD

[Keith Woodworth]

Xenserver 7.2.

 

/sbin/xcp-rrdd suddenly taking up a lot of RAM.

 

Can i just do a:

 

systemctl restart xcp-rrdd

 

on the CLI to restart it? It seems like this process is for gathering/displaying process/perf information.

 

Thanks.

Better to take this XCP-ng specific question to the XCP-ng forum: https://xcp-ng.org/forum/

This is not an XCP-ng issue, that's a core service of Citrix Hypervisor and yes, you can restart it like that, but why do you need to restart it?

Hi. You are right in that this is not an XCP-ng issue.

 

XCP-rrdd a system process and it was chewing up RAM for some reason.

Like so much RAM that XenCenter was throwing errors about that host

being very low on free memory every 30 mins, then it would clear for a bit.

 

When I finally tracked down what was causing it, and this being the

master of the pool, I just restarted the xcp-rrdd process. This fixed the

memory low alarms.

 

I have two other hosts in the pool and are fine. Just this one started

having low memory alarms due to xcp-rrdd suddenly using most of

the memory.

 

Thanks,

Keith

Also, XenServer 7.2 is long out of support now. This issue sounds like one that may have been fixed but you would have to upgrade to at least Citrix Hypervisor 8.2 in order to get a fix.
