Severity: normal
Hi,
When checkarray, the mark "-- MARK --" was not written to the file
"/var/log/messages" by rsyslog and watchdog restarts the server. I have this
problem on several server.
On another server with watchdog not active, I had these messages with the dmesg
command, it was not written in the logs.
