Quick version: gdb /path/to/sbin/squid handle SIGPIPE pass noprint nostop hangle SIG33 pass noprint nostop run -DNYCd3 [wait for crash] backtrace <AW> Thanks for your advise. I will try. Note: The SIG33 line is only if you use aufs on Linux. <AW> Yes, I use aufs (it means I don't need to run SIGPIPE, right?) Thx & Rgds, Awie
