Opened: Aug 12, 2019

Severity: 3-Major

Symptoms

bcm56xxd crashes, and the device fails over on heartbeat error: warning sod[7244]: 01140029:4: HA daemon_heartbeat bcm56xxd fails action is restart. notice sod[7244]: 010c006c:5: proc stat: [0] pid:12482 comm:(bcm56xxd) state:S utime:16612520 stime:879057 cutime:11 cstime:21 starttime:1601425044 vsize:2189299712 rss:527927 wchan:18446744073709551615 blkio_ticks:0 [-1] pid:12482 comm:(bcm56xxd) state:S

Impact

The bcm56xxd daemon may restart and produce a core file. It then continues trying to program the DAG. This causes a system to go offline and stop processing traffic.

Conditions

-- HA configured. -- Programming the DAG while it is under heavy load (i.e., a large number of objects that have to be programmed into the switches).

Workaround

None.

Fix Information

The bcm56xxd daemon no longer crashes while the DAG is being programmed.
