Hi all I'm running a compiled version of Squid 3.4.4 and I'm having some strange behavior lately. I have a two node cluster load balancing via a F5 LB and at times one of the two servers will simply not complete a connection. Squid is running, the logs keep rolling(although much slower and most entries are from it's sibling cache, but no connections go through. A restart of Squid fixes this. As a matter of interest, in my cache logs I see many lines like these 2014/06/25 14:52:58 kid1| WARNING: swapfile header inconsistent with available data 2014/06/25 14:53:28 kid1| WARNING: swapfile header inconsistent with available data On one of my servers I cleaned out the cache, as well as the swap.state file but it didn't make a difference. squid -v output. Squid Cache: Version 3.4.4 configure options: '--prefix=/usr/local/squid' '--sysconfdir=/etc/squid3.4.4/' '--enable-follow-x-forwarded-for' '--with-logdir=/var/log/squid/' '-with-pidfile=/var/run/squid.pid' '--with-swapdir=/var/cache/squid/' '--with-large-files' '--disable-strict-error-checking' '--with-default-user=squid' Can anyone shed some light on this problem? Kind Regards Jasper
