I am using the sslBump and Dynamic SSL Certificate Generation features of squid, below is my configuration for the sslBump

sslcrtd_program /usr/lib64/squid/ssl_crtd -s /usr/local/squid/var/lib/ssl_db -M 4MB sslcrtd_children 5

sslproxy_cert_error allow all

always_direct allow all

ssl_bump client-first all

sslproxy_cert_error allow all

sslproxy_flags DONT_VERIFY_PEER

http_port 3128 ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/etc/squid/ssl/myCA.pem

I am facing below error when i start the squid.

squid -d 23

Is there is any configuration change or work around to resolved this error? Tested with RHEL 6.4 and Fedora 18 with squid 3.2.3, 3.4.4, 3.3.1

I don't think what you've given us is of much use. It tells us that the helper processes are dying, and that it's happening more or less immediately, but doesn't tell us why they are dying.

You might get some clues using strace and/or ltrace. Trace the parent process (probably squid, and forked child processes. (eg strace -f -p PID or strace -ff -p PID). That's likely to show you what those processes are doing immediately before they crash. Try ltrace if strace doesn't give you something useful, but usually strace gives you what you need.

This can be caused by an unitialized ssl_db in squid which can be created with:

ssl_crtd=$(find /usr -type f -name ssl_crtd)
$ssl_crtd -c -s /var/lib/ssl_db
chown -R squid /var/lib/ssl_db

& set in /etc/squid/squid.conf

sslcrtd_program /usr/lib/squid/ssl_crtd -s /var/lib/ssl_db -M 4MB
sslcrtd_children 3 startup=1 idle=1

depending on how your squid was built you may also be able to use security_file_certgen
