hooks fail when php scripts are executed (was Re: Apache refuses to execute hooks after a while in connection with websvn)

I did as much as I could to get to my problem so I can now place a new
question here:

Situation:
suse linux 9.2
mod_dav_svn 1.3.1
Apache 2.0.50 and 2.2
php4 4.4

FSFS repository
pre-commit hook:
#!/bin/sh
echo "test output" >&2
exit 0

Description:
When any php4 script is executed the above pre-commit fails although
this should not be possible. It cannot be a permission problem or
something like that as the hooks are not failing immediately. They fail
in an increasing ratio dependent on the usage of php scripts executed
simultaneously on the server and the amount of commits that take place.

I hacked the subversion sources a bit to get more output when a hook
fails so I know for sure:

1. The hooks are executed as "test output" is given to a client when the
hook fails.

2. The call to apr_proc_wait gives exitwhy==APR_PROC_EXET but an exit
code that is a a fairly large number that is different every time a hook
fails.

3. There are no hanging hook visible when doning `ps ax`

So the hook gets executed but the exit code itproduces is not what
apr_thread_proc returns. To make sure there is no problem with the shell
  on that system I used a binary program that did the same as the hook
script above but it didn't change anything.

I cannot imagine how this all is possible. What else can I do about it.
I cannot reinstall the system as it is a production server. Any comments
what else I could try are welcome.

Thanks

Markus
