[squid-users] RE: [SPAM] - Re: [squid-users] FATAL: Received Segment Violation...dying. (SOLVED) - Bayesian Filter detected spam

There is a bug open for this in bugzilla http://www.squid-cache.org/bugs/show_bug.cgi?id=972 and a test patch against 2.5 stable5 that appears to fix the problem. I was experiencing the same problem several times a day across lots of servers. I have applied the patch and so far so good no crashes.

Violation...dying. (SOLVED) - Bayesian Filter detected spam

I get same error. Squid is 2.5.STABLE5
Compile options:
        --enable-gnuregex --enable-snmp --enable-linux-netfilter --enable-internal-dns --with-pthreads --enable-wccpv2
        --disable-icmp --disable-wccp --disable-arp-acl --disable-ssl --disable-ident-lookups --disable-unlinkd
(transparent proxy using wccpv2, linux-netfilter, etc.).

Here is what I get:
2004/05/19 15:22:16| httpSendRequestEntryDone: Likely proxy abuse detected 'x.x.x.x' -> 'http://activex.microsoft.com/objects/ocget.dll'
FATAL: Received Segment Violation...dying.

After this squid restarts.
What can it be?
