Dump analysis showed the system crash occurred when dereferencing an object in one of the process objects maintained by the SISIPS Kernel module. This crash occurred under low memory conditions. On the impacted Linux servers, Bash.daudit (Centrify Direct Audit) process's behavior of switching between multiple users triggered a buffer overrun problem in the SISIPS kernel module's Root Accountability Feature implementation, leading to the crash.
