Hey Guy, All
I have started facing a very similar issue now.I have been using
squid-3.HEAD-20120421-r12120 for about 5 months without any issues.
Suddenly from yesterday ive started getting crahses in ssl_crtd
process.
In my case i am the only user but i observe that the behaviour is
random. Sometimes it crashes and sometimes it works. Different https
pages give the crash. Even non https pages have caused the crash.
These occur especially on google https pages like docs,mail,calender etc..
The signing cert is also ok and has NOT expired.
My squid conf looks like this:
*******************************************************
sslproxy_cert_error allow all
sslcrtd_program /usr/local/squid-3.3/libexec/ssl_crtd -s
/usr/local/squid-3.3/var/lib/ssl_db -M 4MB
sslcrtd_children 5
http_port 192.168.8.134:3128 ssl-bump generate-host-certificates=on
dynamic_cert_mem_cache_size=4MB
cert=/home/asif/squid/www.sample.com.pem
key=/home/asif/squid/www.sample.com.pem
http_port 192.168.8.134:8080
https_port 192.168.8.134:3129 ssl-bump generate-host-certificates=on
dynamic_cert_mem_cache_size=4MB
cert=/home/asif/squid/www.sample.com.pem
key=/home/asif/squid/www.sample.com.pem
*******************************************************
The ssl_db directory is initialized properly with correct permissions.
***********************************************************
[talha@localhost lib]$ pwd
/usr/local/squid-3.3/var/lib
[talha@localhost lib]$ ls -al
total 24
drwxrwxrwx 3 root root 4096 Sep 20 15:31 .
drwxrwxrwx 6 root root 4096 Sep 20 15:05 ..
drwxrwxrwx 3 nobody talha 4096 Sep 20 15:31 ssl_db
The size file also has some values in it and cert generation also
seems to work but suddenly it all crashes .

Now that I think about it, I don't remember if this works for ssl_crtd though -- seems like I have had to start "gdb ssl_crtd" and then attach to one of the ssl_crtd processes, then generate HTTPS traffic to trigger the request to ssl_crtd and get a backtrace when ssl_crtd gets the segfault signal…
