I've been running squid-5 and squid-6 (both release and HEAD) on my old proxy farm. Four machines, ubuntu bionic. All was well, except for the occasional crash. I filed bug reports, and the preliminary patches helped with the crashes: https://bugs.squid-cache.org/show_bug.cgi?id=5055 https://bugs.squid-cache.org/show_bug.cgi?id=5056 Recently, I set up a new cluster of four up to date machines with new hardware (still ubuntu, focal though, still x64, assloads of CPUs and memeory) and tested that cluster with the users from our department. All went well, squid never once crashed. Then we took the old cluster offline, and let the new cluster take over. Now I'm getting (with the same hand-build squid versions!) a LOT (about once every 15 Minutes) of crashes like this one: 2020/09/22 09:34:07| FATAL: check failed: opening() exception location: tunnel.cc(1305) noteDestinationsEnd current master transaction: master359979 My infrastructure generates backtraces upon crash, but in the case I'm not getting any. Which is odd, given I start squid in gdb with "/usr/sbin/squid -sYNC" -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netzwerk Campus Benjamin Franklin (CBF) Haus I | 1.
