[squid-users] Any tips on analysing squid crashes?

I have a squid that falls from the sky once a week. It is running with -C to provide coredumps, however, the coredumps contain only:

Solaris 2.9 pstack output:
core 'core.squid' of 14292: (squid) -YC -f /etc/squid3.conf
 ffffffff7dba8ddc _kill (ffffffff7e10dac8, ffffffff7e10cc38, 1127bc, 10604c, 2, ffffffff7e10dac8) + 8
 ffffffff7e0064d4 __1cH__CimplRdefault_terminate6F_v_ (ffffffff7e10dac8, ffffffff7e10cc38, 190298, 10604c, 104e40, ffffffff7e0064d0) + 4
 ffffffff7e0062b4 __1cH__CimplMex_terminate6F_v_ (ffffffff7e10de40, 0, 0, ffffffff7e10de40, ffffffff7e10c978, 1) + 24
 ffffffff7e007078 _ex_rethrow_body (ffffffff7e10de40, 1, 0, 105984, ffffffff7e4c0608, 100272ba8) + 88
 ffffffff7e006fc8 __1cG__CrunKex_rethrow6F_v_ (100514d50, 1000c9640, 100514d50, ffffffff7e10de40, ffffffff7e4c8528, 1) + 40
 000000010014d0b4 $XDGBaHss9zzMWWh.__1cNSquidMainSafe6Fippc_i_ (4, ffffffff7ffffc18, ffffffff7ffffc40, 0, ffffffff7e10dec8, 100514d50) + 94
 00000001000714dc _start (0, 0, 0, 0, 0, 0) + 17c

This appears to be saying that a 'catch' handler in SquidMainSafe was
triggered, yet nothing appeared in the errorlog, and nothing in the stack
hints as to why it died.

Also does anyone have any rough estimate of CPU usage of squid3 vs squid2?
It looks like squid3 takes more CPU than squid2.
