Opened: Dec 10, 2015
Severity: 3-Major

Symptoms

Rarely, you might have ASM synchronization configured, but there is no evidence that the synchronization is occurring, and the policy changes are not synchronized. The following messages can be seen in '/var/log/ts/asm_config_server.log': ------------------------- F5::ASMConfig::Handler::SyncHandler::sync_general_ucs_request,,ASM is now entering sync recovery state. Requesting complete configuration from /Common/<peer_machine_name> F5::ASMConfig::Handler::send_to_relay,,Failed on sending sync_send_ucs to /Common/<peer_machine_name>: Can't call method "send" on an undefined value at /<path>/Handler.pm line <line_number>. F5::ASMConfig::Handler::spawn_relay_handler,,Sync recovery state timed out. State may be inconsistent with other peers ------------------------- Please notice the values in '<...>', in the log examples above, which may differ.

Impact

ASM sync does not occur

Conditions

It is not known what triggers this, but it occurs when ASM is provisioned, ASM sync is enabled, and HA pair is configured. It is possible that it occurs when mcpd memory consumption becomes excessive.

Workaround

None
