syslog-ng : STAT dropped 0

[Jack Vo]

Hi all,
I'm using HP RX7640 and OS - Suse Linux Enterprise Server 10.
The server always automatically restart each hour.

This is the log file about syslog-ng, I don't know what it means. Can anybody help me to understand about it ???

[Matti_Kurkela]

"STATS: dropped 0" means that within the last hour, there has been zero occasions where syslog-ng would have dropped a message. That would happen if there would have been too many messages to handle, or if syslog-ng would have been configured to ignore some messages.

In other words, everything is just fine, unless you actually _want_ to drop some of the log messages you're receiving...
