[squid-users] A lot of open rewriter heplers and are hanging! Squid 3.5

[Ulises Nicolini]

  Hello,

I have migrated from Squid 2.7 to Squid 3.5 in a heavy  traffic 
enviroment (150 http request per second, and more than 1200 clients), 
using trpxy configuration.

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'

I use  jesred rewriter (http://www.linofee.org/~jel/webtools/jesred/). 
This applications was modified to match the output format requested by 
squid 3.5 (example OK 
store-id=http://app.updates.avast.com.SQUIDINTERNAL/jrog2-c40-c3f). This 
is the input and output format that jsred log in file

The problem is that after several hours of running squid, the process 
list (ps -aux command)  is filled with hanging jesred !

This is the portion of squid configuration

/store_id_program /sysmgr/squid/jesred//
//store_id_children 20 //
//store_id_bypass on/

And this is my process list after three days!!!

Any ideas?

Thanks!

Ulises
