You specified the wrong path (the correct one is /var/cache/squid/ssl_db ). 


good catch:
now running:
  sudo -u squid /usr/libexec/squid/security_file_certgen -s /var/cache/squid/ssl_db -M 4MB 
^C
produces nothing.
That lack of output is a good sign -- the helper managed to start successfully.

Helpers are still dying, but it looks like they do it while handling traffic. 



2. Redirect security_file_certgen stderr (but not stdout!) output
into a dedicated log file. It may be possible to do that right on
the sslcrtd_program line, without wrapping the helper into another
script.



how to do that?
Try using shell redirection when specifying how to run the helper. Something along these lines may work: 

    sslcrtd_program /usr/local/... -M 4MB >> /tmp/sslcrtd.error.log
My bad. I missed "2" to redirect stderr rather than stdout. Fixed below. The missing file descriptor is _not_ the reason your test is not working though (as detailed below). 



now the configuration looks like this:
sslcrtd_program /usr/libexec/squid/security_file_certgen -s /var/cache/squid/ssl_db -M 4MB >> /tmp/sslcrtd.error.log 


To capture stderr:

sslcrtd_program /usr/libexec/squid/security_file_certgen -s
/var/cache/squid/ssl_db -M 4MB 2>> /tmp/sslcrtd.error.log



in tmp there is no sslcrtd.error.log file.
AFAICT, your Squid does not start sslcrtd_program helper. What does "squid -v" say? If there is no '--enable-ssl-crtd' there, then you need to rebuild your Squid executable from scratch. Also, at least one http_port or https_port directive in your squid.conf should have both "generate-host-certificates" and "ssl-bump" options.
When done right, you should see the debugging file created in /tmp/ and, in cache log, Squid logging "Starting ..." lines mentioning your helper (similar to your existing lines for the ufdbgclient helper). 


HTH,

Alex.

To recreate a certificate database you should do:

sudo rm -rf /var/cache/squid/ssl_db
sudo /usr/libexec/squid/security_file_certgen -c -s /var/cache/squid/ssl_db -M 4MB 
sudo chown -R squid:squid /var/cache/squid/ssl_db

    We need to figure out why your security_file_certgen helpers are
    exiting. IIRC, those helpers have not been upgraded to report their
    fatal failures to cache.log. There are a few tricks you can use to
    see
    what the problem is, but I would probably start with these three:
    1. Run security_file_certgen with sslcrtd_program parameters from the     command line, as Squid user. If you are lucky, it will complain about 
    something before it starts waiting for the helper request.

    2. Redirect security_file_certgen stderr (but not stdout!) output
    into a
    dedicated log file. It may be possible to do that right on the
    sslcrtd_program line, without wrapping the helper into another script. 

    3. Enable full debugging, reproduce the problem with a single
    transaction, and send a link to the corresponding compressed
    cache.log
    file for analysis as detailed at
https://wiki.squid-cache.org/SquidFaq/BugReporting#debugging-a-single-transaction


    Cheers,

    Alex.
