I am getting such messages in syslog.
rsyslogd-2177: imuxsock lost 21869 messages from pid 3418 due to rate-limiting
rsyslogd-2177: imuxsock begins to drop messages from pid 3427 due to rate-limiting
My server is becoming unresponsive for last few days and I have to reboot the machine 2-3 times.
Please let me know what these messages could be and if these messages can be the reason for server going down.
