As we ca see I'm having exception, which are handled by
ICAPModXact::noteCommRead method. Seems like this exception caught in
Must(commStatus == COMM_OK); (334: ICAPXaction.cc)

Does anybody have experienced something similar and know how to solve
this ?

Btw I'm using squid with following configuration options:

Squid Cache: Version 3.0.STABLE17
configure options: '--prefix=/opt/squid3S17p1' '--enable-icap-client'
'--enable-large-cache-files' '--enable-storeio=ufs aufs diskd'
'--enable-disk-io=Blocking AIO DiskDaemon DiskThreads' '--enable-snmp'
'--with-large-files' '--with-large-cache-files'
'--with-filedescriptors=16384'

Any ideas/comments would be appreciated.

Thank you.
