Veritas Cluster Server (VCS) agent entry point processes (e.g. monitor) are killed by signal 9 (SIGKILL) when Linux audit rules like the following are configured.

# log all commands executed by an effective user id of 0 (root).
-a exit,always -F arch=b64 -F euid=0 -S execve -k rootcmd
-a exit,always -F arch=b32 -F euid=0 -S execve -k rootcmd

This causes the corresponding VCS resources to go into UNKNOWN state or report as NOT PROBED.

Error Message

The following messages are logged in the VCS agent log.

This is a Linux kernel issue.  The problem can happen to any process with a lengthy program argument list.  The problem was reported to occur on the following kernel versions.

2.6.32-642.15.1.el6.x86_64  (RHEL 6.8)
2.6.32-696.el6.x86_64  (RHEL 6.9)


As a temporary workaround please disable the audit rules similar to the ones listed above or disable audit altogether.

Please contact the OS vendor for a permanent solution.
