Hello
thank you very much for your help.
the problem occurred once the process size reached 4Gbytes. the only
application running on the server is the proxy, there are two
instances running each one in a different IP address.
there is no cache.. the squid was compiled with
--enable-storeio=diskd,null and in squid.conf :
cache_dir null /var/spool/squid1
as for the hits i assume there are none since there is no cache am I wrong?
here is what i get with mgr:info output from squidclient:
Cache information for squid:

I am not able to find a core file in the system for the problem of yesterday.
the squid was restarted yesterday at 11.40 am and now the process data
segment size is 940512 KB.
i bet that if i let the process to reach 4GB again the crash will
occur? maybe is this necessary in order to collect debug data?
thank you in advance for your help it is very much appreciated.
kindest regards

You may have hit a malloc problem seen in recent FreeBSD 64-bit.
Check what the OS reports Squid memory usage as, in particular VIRTSZ,
during normal operation and compare to those internal stats Squid keeps.

Hello
i have used all the internet resources available and I still can't
find a definitive solution to this problem.
we have a squid running on a solaris 10 server. everything run
smoothly except that the process size grows constantly and it reaches
4GB yesterday after which the process crashed; this is the output from
the log:
FATAL: xcalloc: Unable to allocate 1 blocks of 4194304 bytes!
[...]
i am eagestly looking forward for your help
It seems like you're being hit by a memory leak, or there are some
serious configuration problems.
How often does this happen, and how much load is there on the system?
(in hits per second or minute, please)
Going 64-bit for squid isn't going to solve things, at most it will
delay the crash but it may cause further problems to the system
stability.
Please see http://wiki.squid-cache.org/SquidFaq/BugReporting for hints
on how to proceed.
