Mark,

I had the same issue with some very verbose iocs.  What I did to solve this was by using logrotate to manage the log files.  Here's the basics of my config (note you can rotate on size too):

# /etc/logrotate.d/softiocs
<path to logs>/*log {
    notifempty
    copytruncate
    daily
    rotate 7
    dateext
    compress
}

Log files end up like this:
-rw-r--r-- 1 epics clas-3 311M Jun  2 16:41 iocsvtDaqDpm0.log
-rw-r--r-- 1 epics clas-3 4.2M May 27 04:12 iocsvtDaqDpm0.log-20150527.gz
-rw-r--r-- 1 epics clas-3 2.1M May 28 04:09 iocsvtDaqDpm0.log-20150528.gz
-rw-r--r-- 1 epics clas-3 2.3M May 29 04:06 iocsvtDaqDpm0.log-20150529.gz

Subject: Rotating or deleting procServ log files

Ralph,

 

procServ log files sometimes get very large, so we would like to rotate them, and or delete them and start a new one without restarting the procServ process.

 

Is this possible?  I found that if I rename the log file procServ just kept writing to the renamed file.  If I delete the log file procServ does not create a new one, it just silently continues without logging anything.

 

Is there a correct way to replace the current log file without restarting the procServ process?

 

This is procServ 2.6.0.

 

Thanks,

Mark
