FWIW,
It may be that our issue was this:
http://www.freebsd.org/cgi/query-pr.cgi?pr=78776
What I have since then tried:
- setting up irqs as sources for /dev/random pool, (in my case vmstat -i shows a lot of activity at 2, 10, 0 and 8, and I used the first two with rndcontrol and then in rc.conf w/ rand_irqs=)
- installing prngd, and using it for SSL seeding
- replacing SSLRandomSeed with different values (egd, builtin, urandom)
At first. just commenting out the openssl php module didn't work, but now that I have more activity in /dev/random due to using irqs, removing openssl php module was apparently a sufficient short-term fix for my problem at least.. and it works now.
However, I have no idea why it had suddenly ceased working; if I'd have to guess, this might have had something to with php4's openssl revision 1.84 at ports/lang/php4/Makefile (a compilation option to build openssl statically).
HTH..

I've started to experience the same thing which Kyle Mott and "Vlad" reported with apache+mod_ssl crashing when SSL is enabled:

A few salient points: - running FreeBSD-4.11 stable, and the latest apache+mod_ssl port w/ PHP - the crash occurs before httpd creates the child processes - disabling PHP does not work; disabling SSL works around this problem (but is not an acceptable solution, of course :) - I don't have any cryptocards, nor have I made any significant changes to the system since this started happening. The system uptime was around 40 days, so the process has at least started fine 40 days ago. - rebuilding world and apache+mod_ssl does not help - /dev/{u,}random seem to be fine - my /tmp is mounted nodev,noexec,nosuid but this has worked with it in the past, so should not be an issue.
