Troubleshooting
Problem
The sniffer is crashing continuously on IBM Security Guardium appliances where either sniffer patch p4009 (SqlGuard_11.0p4009_SnifferUpdate_Jul-09-2020) has been installed (for V11), or sniffer patch p4054 (SqlGuard_10.0p4054_SnifferUpdate_Jul-09-2020) has been installed (for V10).
The issue has been particularly observed if the installed Policy contains a rule with a condition on the Command entity, or in other words, if a Command criteria is defined in the Policy rules.
A message similar to the following may be logged in the messages log every few minutes:
segfault at <string> ip <string> sp <string> error 4 in libtcmalloc.so.4.4.5[xxxxxxx+xxxxxx]
Symptom
Sniffer continuously crashes and segfault message is logged to the messages log every time it crashes. Additionally, the IBM Guardium S-TAPs connected to the collector continuously disconnect from and reconnect to the appliance while messages indicating that are logged to the STAP.log.
