Re: [squid-users] Squid 2.6 STABLE 16 also crashing

Hi Adrian,

I get the following stack traces. I had changed the refresh_pattern a while
back so my current refresh_pattern:

refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern . 300 99% 2880

Stack Traces:

Program received signal SIGSEGV, Segmentation fault.
