Hi,
I run squid as a non-daemon process, with the following command-line:
/usr/sbin/squid -f ~/etc/squid/squid3_sbaddah.conf -N -u 0
Sporadically I find squid aborting with; Aborted (core dumped).
I've attached the last stackdump for this. Running addr2line against
both cygwin1.dll and squid.exe, I get the following backtrace:
/usr/src/debug/cygwin-1.7.29-2/winsup/cygwin/exceptions.cc:765
/usr/src/debug/cygwin-1.7.29-2/winsup/cygwin/exceptions.cc:1463

/usr/src/debug/squid-3.3.3-1/include/RefCount.h:77
/usr/src/debug/squid-3.3.3-1/include/RefCount.h:60
I can see that this is due to a failed assertion in store_swapout.cc:
assert(e->swap_status == SWAPOUT_WRITING);
I haven't really taken careful note of every crash, bit it seems that
most of the aborts happen after my laptop comes out of a sleep.
It's not a big problem. The crashes aren't too frequent. But thought it
might help to have it reported in case it offers clues to more serious
issues.
