Symptoms

APMD memory grows over time causing OOM killer to kill apmd

Impact

APMD memory grows over time and OOM killer may terminate apmd thereby affecting traffic. Access traffic disrupted while apmd restarts. If APMD is not killed by OOM killer the system may start thrashing and become unstable, generally resulting in cores from innocent processes that are no longer scheduled correctly - keymgmtd, bigd, mcpd are typical victims. Ultimately system may restart automatically as watchdogs fail.

Conditions

Access policy has resource assignment agents/variable assignments

Workaround

None
