[squid-users] Solaris Core Dump Issue / Debug Issue

Scenario:
I configure a squid cache server as a transparent reverse proxy based on
the instruction in
 
http://squid.visolve.com/white_papers/reverseproxy.htm
 
 
When users type a URL on their browsers, the local dns server maps the
host address to the proxy server and the request is sent to the proxy
server, then the proxy server retrieves the content and sends back to
the browsers.
 
But when they type a valid url and retrieve the content successful, and
then switch to a url pointing to a bogus web server, the squid server
generate core dumps constantly.
 
I notice when the core dump happens, the debug option in the conf is
debug_options 33,9
 
If I change it to
debug_options 21,9
 
I don't see squid crash any more, does anyone know why?
 
Environment:
Ultrasparc running Solaris 8 (Generic_108528-18 sun4u sparc
SUNW,UltraAX-i2) and squid version is 2.5 release 4
Gdb stack:
#0 0xff01f7cc in _libc_kill () from /usr/lib/libc.so.1
(gdb) where
#0 0xff01f7cc in _libc_kill () from /usr/lib/libc.so.1
#1 0xfefb58f4 in abort () from /usr/lib/libc.so.1
#2 0x6adf4 in sigusr2_handle (sig=11) at tools.c:303

Here is the diff file between the modified squid conf file and original
conf file.
