Situation

After CIFS has been running for awhile, resources (volumes/files/directories) can no longer be accessed via CIFS. In checking the cifs.log file, the following is seen:

CIFS[22370]: EVENT: ENTRY: NBNS SIGTERM handler is waiting for NBNSUDPReceiveRoutine
CIFS[22370]: EVENT: NBNS: SHUTDOWN: nbns main thread waiting for SigTermHandlerThread
CIFS[22370]: EVENT: NBNS: NBNSReleaseNames: Cleared NetBIOS name "SERVER01       " from NBNS list
CIFS[22370]: EVENT: NBNS: NBNSReleaseNames: Cleared NetBIOS name "SERVER01       " from NBNS list
CIFS[22370]: EVENT: NBNS: NBNSReleaseNames: Cleared NetBIOS name "MYDOMAIN       " from NBNS list
CIFS[22370]: EVENT: NBNS: SHUTDOWN: nbns exiting from main thread
CIFS[22370]: EVENT: ENTRY: SHUTDOWN cifs is exiting from main thread

Resolution

This has been reported to engineering.

Cause

A process is sending a SIGIO to the CIFS process. CIFS responds by shutting down.
