Opened: Jun 24, 2019
Severity: 3-Major

Symptoms

After a reboot or restart of services, gtmd may fail to update tmms on secondary blades of the state of a pool or wide IP. This can occur when tmm has failed to load the full GTM configuration at the time that the state change occurs. With tmm debug logging enabled you may see logs like: -- alert gtmd[12211]: 011a3004:1: SNMP_TRAP: Wide IP /Common/wideip-9998.com state change blue --> red (No enabled pools available) -- debug tmm[20057]: 011ae0f9:7: Encountered problem while processing mcp message at ../gtmdb/db_gtm_wideip_state.c:88 : Wideip not found during attempt to set state. Will reprocess message later. If the configuration still fails to load the object after 60 seconds, the message may be deleted and the state change is lost.

Impact

Wide IP queries may give different results depending on which blade the query hits.

Conditions

- Multi-bladed system. - Reboot or restart of services. - tmm is slow to load configuration due to size (e.g., because of many thousands of objects).

Workaround

Increase the tmm.mcp.replay.timeout: tmsh modify sys db tmm.mcp.replay.timeout value 240

Fix Information

None
