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
Input string->1430313641.311 Input String:

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
