Hi, recently I'm facing too many ERROR: Collapsed forwarding queue overflow for kid2 at 1024 items lines in my Squid 5.2 log files. So far I was able to find it in the CollapsedForwarding.cc func Broadcast as a result of a full queue which limits beeing defined by the QueueCapacity const at 1024 items. Now I have squid in VM with 6 CPU cores, 16GB RAM and 2 workers and 4 diskers with rock (various slot sizes). /var/run/shm squid-cf*.shm files exist. Mounted with shm /dev/shm tmpfs nodev,nosuid,noexec,size=8G 0 0 (is 8GB enough or too much?) I have collapsed_forwarding on Could someone elaborate how the queue is filled - what is clogging it? What can be done to work it out? I don't mind too much if I have to turn collapsed forwarding off - as I don’t see any significant gain. On the other hand I don't see any slowdown (because of non-cacheable object being forwarded individually) either. Thanks!
