Reported By: [EMAIL PROTECTED]
Status: Open
Bug Type: Apache2 related
Operating System: Solaris x86 2.7
PHP Version: 4.4.0-dev
New Comment:
- tested on Solaris 2.7/SPARC: fails too
- gave up trying to build Apache 2.0.43 with an alternate threads
library: can't get MIT pthreads to build
- Sunsolve mentions bug causing SIGPROF not to be delivered
in certain cases, but this only concerns the "alternate" threads
library on Solaris 2.8. Nothing related to 2.7. I've tried to install
the latest Solaris 2.7 libthreads.so.1 patch: doesn't solve the problem

No module/extension besides the ones shown in the configure command
line above (rewrite, expires, status, info). The configuration of the
FreeBSD test box is a copy of this one, and it works. Could it be that
the threads library itself is either taking over SIGPROF of blocking it
somehow?
I'm considering building Apache with an alternate threads library to
see what happens.

Sounds like some is taking over the handler for the SIGPROF and it
never gets to PHP. Besides PHP, what modules/extensions do you have
enabled in your Apache?

Works on FreeBSD 4.x (with unmodified PHP source).
So it's kind of Solaris-specific (will test on Sparc)

[oops, posted this as "add comment" because I hadn't read the direction
to use "edit submission" instead yet --sorry]
Just out of curiosity, and admittedly not quite understanding what I
was doing, I have tried changing the zend_set_timeout code to use
SIGALRM instead of SIGPROF and thus pass ITIMER_REAL to setitimer
instead of ITIMER_PROF
Guess what? It works now.
I understand that this can have nasty side effects. I was just
wondering why SIGPROF was being used and if this could be the reason.
The setitimer man page on Solaris says a lot of things about using it
in MT environment which I don't quite catch :-)
