Severity: 3-Major

Symptoms

When the access profile configurations in APMD and MCPD are out of sync, APMD detects that the config snapshot for one access profile is missing. This triggers AMPD to recreates the config snapshots for all access profiles. The detect-recreate cycle repeats every minute, posting log messages: -- err apmd[18013]: 01490259:3: Exception occurred for memcache operation: AccessPolicyProcessor/ProfileAccess.cpp line:492 function: resetTimeout - Config snapshot for profile /Common/ap could not be found using key tmm.session.a9735a75704_0ooooooooooooooooooo ... -- notice apmd[18013]: 014902f3:5: (null):Common:00000000: Successfully created config snapshots for all access profiles. ... -- err apmd[18013]: 01490259:3: Exception occurred for memcache operation: AccessPolicyProcessor/ProfileAccess.cpp line:492 function: resetTimeout - Config snapshot for profile /Common/ap could not be found using key tmm.session.a9735a75704_0ooooooooooooooooooo ... -- notice apmd[18013]: 014902f3:5: (null):Common:00000000: Successfully created config snapshots for all access profiles.

Impact

TMM memory usage increases due to excessive config snapshots being created.

Conditions

The conditions under which the access profile configurations in APMD and MCPD become out of sync is unknown.

Workaround
