RTMT Alert : LowSwapPartitionAvailableDiskSpace on 10.5 CUCM

[fei he]

Hi All

We recently received alerts of LowSwapPartitionAvailableDiskSpace for our CUCM 10.5 and research suggest that we are hitting a bug CSCva41819 which did not suggest any workaround to clear this alert apart from monitoring it (_https://bst.cloudapps.cisco.com/bugsearch/bug/CSCva41819/?referring_site=bugquickviewredir).

By chance you guys has a real workaround to resolve this alerts?

A restart of the server should clear the alert. Long term you will need to upgrade to a fixed release to permanently fix the problem.

Thanks for response. What could be impact if we leave this alerts going?

Fei

[Brandon Buffin]

The swap partition is part of virtual memory and used as an overflow for physical RAM. The impact will likely be minimal. I would recommend you schedule a maintenance window to restart the server and put restarting on your list of regularly scheduled tasks.

Will this alarm could cause phone reset itself randomly?

[Brandon Buffin]

I suppose it's possible if the server runs out of physical memory and has no space on the swap drive to expand. I would recommend scheduling the restart before the swap drive runs out of space completely.

Thanks Brandon.

We end up reboot impact nodes to bring swap partition disk space back to normal.
