Sadly /usr/apache2/bin/apachectl and httpd are delivered as 32-bit only.

I saw this issue a lot. I worked at a place that served webpages that literally had 200+ server side includes, and opened dozens of logfiles. Back then the only solution was to upgrade to 64 bit.

the standards define FILE to be opaque, posix shouldn't care.

I seem to recall the issue is that FILE would change size on applications.

(I also vaguely recall this only being an issue for the 32bit ISAs?)

@Geoff: It could be, yeah. Depends if WordPress was trying to do it all within PHP using sockets & SMTP, or if it was making an exec() call to /usr/lib/sendmail.

@heavygirl: Nope, don’t blame Solaris. Blame POSIX.

Ugh, 256 default FD limit in a multithreaded, “modern” and “advanced” OS in 2007. Isn’t this silly?

So is this the explanation for WordPress not consistently sending email notifications of blog events?

Yeah – I looked at trying to do it with smf properties and svccfg – but couldn’t figure out how because of the ulimit.

It it wasn’t for the ulimit you could have done this in the much more supported (and not going to get blown away on upgrade) way of setting the environment variable using svccfg.
