Several times in the last 8 days our main proxy has died 3 times with
the following logged in cache.log:

There is no core file being produced. The above crash happened during
working hours, but as some have occurred outside busy periods, I don't
think it is traffic-related.
Details of the build being used are:
Squid Cache: Version 2.5.STABLE1-20021118
configure options: --enable-dlmalloc --enable-gnuregex
--enable-async-io=160 --enable-useragent-log --enable-referer-log
--disable-wccp --enable-snmp --enable-poll
--enable-err-languages=English '--enable-removal-policies=lru heap'
Together with:
SmartFilter Info: SmartFilter Version: 3.1.1.02
SmartFilter Info: SmartFilter API version: 3.1.3
Via the SmarFilter patches supplied by Secure Computing.
It was all built using gcc 3.2 (with the Sun linker) on Solaris 7.
A similar build without the SF patches and running on Solaris 2.6 hasn't
had this problem (it is the parent of the above in our DMZ.) In
addition, this symptom did not occur prior to 8 days ago (we have been
running the current config since December 22 and the only changes to SF
have been the site.txt file and weekly control list updates.)
Has anyone seen this symptom? In case it is SF-related I am also asking
Secure Computing.
