On a 7606 router, a 7600-SIP-200 module with SPA-2XT3/E3 installed lost both DS-3 circuits after getting the error message:
SLOT 2: Aug 2 02:11:27.725 UTC: %SSA-5-FABRICSYNC_REQ: Fabric sync
requested on Primary channel (2)
SLOT 2: Aug 2 02:11:27.725 UTC: %SSA-4-FABRICCRCERRS: 5 Fabric CRC
error events in 100ms period
The only way to recover the circuits was to issue the command: hw-module module 2 reset
CCO documentation says that the Fabric error messages are informational and require no action.
Has anyone seen this before or have suggestions on how to avoid losing circuits again?
