I've installed 2.5.STABLE9-20050404 on over 30 servers, each running RedHat Linux 2.1 AS on Intel Xenon CPUs. They've been running since Monday morning at 12:30 AM EST. Since then I've gotten 6 mail messages from the squid process saying I've encountered a fatal error. The cache.log file says it's a segmentation violation. I have yet to see the same server die twice. I haven't found a core file to examine. I build squid with the following options: --enable-cache-digests --enable-underscores --with-pthreads --enable-storeio=aufs --enable-removal-policies --enable-gnuregex Has anyone else seen this problem? I didn't have this problem with 2.5STABLE9. Mike Mitchell SAS Institute Inc. Mike.Mitchell@xxxxxxx (919) 531-6793
