stats.log is not getting updated regularly

Hi Experts,

We are facing an issue with Stats.log in our Webmethods 8.2 integration server.
Stats.log is not getting updated regularly even though transactions are occuring on server regular basis
We are using Developer’s built in Events to track whether stats.log is getting updated periodically or not.

This issue got fixed temorarily after server restart but it keeps on coming back.

Has anyone seen similar issue like this.

Thanks,
Amit

check these server config:
watt.server.log.queued
Specifies whether the server is to queue log entries written by its facilities in memory,
then use a background thread to write them to the server log. The default is true (queue
log entries). For complete information, see the webMethods Audit Logging Guide.
watt.server.log.refreshInterval
Specifies the length of the refresh interval (in seconds) for log entries. The default is 90
seconds. For complete information, see “Changing the Display Permanently for All Logs”
on page 150.

see if make any differences
