S 09:18 0:04 (ssl_crtd) -s /var/lib/squid/ssl_db -M 16MB I saved the output of 'strace /usr/sbin/squid -YC -f /etc/squid/squid.conf -n squid' if you require it. The command "squid -n squid -d 9" doesn't seem to change the logging output, at least not immediately. I see lines such as the following in the log: kid1| BUG: Unexpected state while connecting to a cache_peer or origin server kid1| WARNING! Your cache is running out of filedescriptors kid1| WARNING: 10 pending requests queued kid1| Queue overload, rejecting kid1| WARNING: All 10/10 ssl_crtd processes are busy. kid1| WARNING: Consider increasing the number of ssl_crtd processes in your config file. kid1| comm_open: socket failure: (24) Too many open files kid1| helperDispatch: invalid callback data This is the sslcrtd_program I'm using: sslcrtd_program /usr/libexec/squid/ssl_crtd -s /var/lib/squid/ssl_db -M 16MB sslcrtd_children 10 I don't remember why I set it to 10. Probably a bad idea since the default is "sslcrtd_children 32 startup=5 idle=1". So, I'm going to either comment out sslcrtd_children, or change it to: sslcrtd_children 64 startup=10 idle=2 Could this alone explain the issue I'm seeing?
