Symptoms

bigd processing FQDN node monitors may crash due to a timing issue when processing probe responses.

Impact

bigd crashes (SIGSEGV). The system restarts bigd automatically, and monitoring resumes. No other action is needed.

Conditions

bigd is configured for FQDN node monitors.

Workaround

Although no workaround is available for bigd configured for FQDN node monitors, this crash occurs due to a timing issue, and should be rare.

Fix Information

bigd no longer crashes (SIGSEGV) when running FQDN node monitors due to a timing issue.
