Got a couple of these yesterday. When I searched the forum, a post from 2011 suggested that updating to 9.2.1 would increase the buffer to 500 thousand; however this is well below that amount.
Syslog Alarm: 41596 messages overflowed the message queue this hour.
The current maximum threshold is set at 1 messages per hour.
This could indicate a problem, please check the log files and syslog statistics below.
