________________________________ From: Amos Jeffries <squid3@xxxxxxxxxxxxx> > > cache_log is one of the Squid directives which require a unique file path+name per instance when running multiple instances. I defined a unique name for this directive for each squid service (squid.conf used by the failing caching proxy: not defined -> default value): # grep cache_log squid.*.conf squid.http.conf:cache_log /var/log/squid/cache.http.log squid.https.conf:cache_log /var/log/squid/cache.https.log squid.owa.conf:cache_log /var/log/squid/cache.owa.log squid.owa2.conf:cache_log /var/log/squid/cache.owa2.log # grep pid_filename squid.*.conf squid.http.conf:pid_filename /run/squid.http.pid squid.https.conf:pid_filename /run/squid.https.pid squid.owa.conf:pid_filename /run/squid.owa.pid squid.owa2.conf:pid_filename /run/squid.owa2.pid # grep access_log squid.*.conf squid.http.conf:access_log none squid.https.conf:access_log none squid.owa.conf:access_log none squid.owa2.conf:access_log none I also just added unique_hostname for all reverse proxies, but did not define it for the "failing" proxy cache: unique_hostname rev_https unique_hostname rev_http unique_hostname rev_owa unique_hostname rev_owa2 The man page states: -n name Specify Windows Service name to use for service operations, default is: Squid I didn't know it could be used in Linux. So I set it up as you suggested (thanks for pointing me to the Multiple Instances wiki page). I modified my init scripts with the -n option. I also checked the squid logs to confirm that the service names were properly set. eg. for one of the reverse proxies: kid1| Service Name: squidhttp So, after applying everything: # ps aux | grep squid root 19635 0.0 0.0 84856 5116 ?
