I have this isssue with trixbox 2.0, queuemetrics and 2X4ports wildcard fxo, i have followed the steps to eliminate rotation of the queue_log files.
In sundays starting 11:00 am ( no known cron jobs and veryfied with webmin) it start creating files queue_log and event_log at ranges of 1 per second, the files are empty only have the header of the page, and it can be since 40000 to 155000 the other day, it generates a work load that crash the machine and when it restarts takes like 10 minutes to 25 minutes to assing permissions on /var/log/asterisk/, have anyone some similar problem?
In the rest of the week i have no problems.
