ONTAP Node fails and won't start with error on boot: “PANIC: Process vifmgr unresponsive for xxx seconds in process nodewatchdog on release 9.x”

Last Updated:

Applies to

  • ONTAP 9.x
  • Data ONTAP 8.x
  • Data ONTAP operating in 7-Mode


  • The node panicked due to vifmgr not responding before the watchdog timed out and was unable to recover the mdbs when it rebooted:

Panic String: PANIC : Process vifmgr unresponsive for 629 seconds version: 9.1P12

  • The root volume filled up due to high snapshot delta and snapshot space utilization on vol0 resulting from rolling packet trace that was running for 2 weeks:

Mon Mar 30 08:28:37 CDT [nodename: rshd_0: kern.cli.cmd:debug]: Command-line input: The command is 'pktt'. The full command line is 'pktt start a0a-10 -d /etc/crash -m 9018 -b 8m -s 2g -r 12'.

  • Immediately prior to the panic the console log showed that vifmgr and vldb crashed and were unable to restart:

Apr 13 00:49:45 [nodename:spm.vldb.process.exit:EMERGENCY]: Volume Location Database(VLDB) subsystem with ID 34409 exited as a result of signal normal exit (1). The subsystem will attempt to restart.

Apr 13 00:49:47 [nodename:spm.vifmgr.process.exit:EMERGENCY]: Logical Interface Manager(VifMgr) with ID 34415 aborted as a result of signal normal exit (1). The subsystem will attempt to restart.

  • When the node reboots it is unable to recovery the mdbs due to lack of space on vol0:

Apr 13 02:54:46 [nodename:callhome.mdb.recovery.unsuccessful:EMERGENCY]: Call home for MDB RECOVERY UNSUCCESSFUL FOR THE notifyd WARNING.
