Opened: Jul 23, 2021

Severity: 4-Minor

Symptoms

After restarting the ilx plugin, new tmplugin_ilx_rpc_* stat files are being created, but old files are not being deleted. Over time this may result in the /var/tmstat filesystem being filled and F5 daemons not being able to run correctly and this will affect service.

Impact

The presence of too many of these leftover files might prevent merged from rolling up stats and providing graphs and cause such errors: err merged[8523]: 011b0900:3: TMSTAT error tmstat_remerge: Cannot allocate memory. Over time (several days at least) this may result in the /var/tmstat filesystem being filled and F5 daemons not being able to run correctly and this will affect service. When the filesystem is full there will be errors similar to this in ltm log: err diskmonitor[12970]: 011d0004:3: Disk partition /var/tmstat has only 0% free

Conditions
