[squid-users] Very high CPU ussage after migration 2.7 -> 3.5

[Sebastian Goicochea]

Hello,

I have migrated from Squid 2.7 to Squid 3.5 given the fact that I need 
some of the new functions that newer versions have.
The problem I'm having is that squid proccess is using 100% of CPU all 
the time. Cache.log informed squid was low on file descriptors, but 
that's already solved.

Now I see a lot of these in cache.log:

2015/04/17 13:01:07 kid1| Starting new store_id helpers...
2015/04/17 13:01:07 kid1| helperOpenServers: Starting 1/30 'jesred' 
processes
2015/04/17 13:01:08 kid1| Starting new store_id helpers...
2015/04/17 13:01:08 kid1| helperOpenServers: Starting 1/30 'jesred' 
processes

It always says 1/30, is it only using one rewriter? Most of the CPU time 
is idle time, so maybe squid is waiting for something, but I don't know 
what.

squid -v
Squid Cache: Version 3.5.3
Service Name: squid
configure options:  '--prefix=/usr/local' '--datadir=/usr/local/share' 
'--bindir=/usr/local/sbin' '--libexecdir=/usr/local/lib/squid' 
'--localstatedir=/var' '--sysconfdir=/etc/squid3' '--enable-delay-pools' 
'--enable-ssl' '--enable-ssl-crtd' '--enable-linux-netfilter' 
'--enable-eui' '--enable-snmp' '--enable-gnuregex' 
'--enable-ltdl-convenience' '--enable-removal-policies=lru heap' 
'--enable-http-violations' '--with-openssl' 
'--with-filedescriptors=24321' '--enable-poll' '--enable-epoll'


Any ideas?


Thanks,
