Its a few programs, made in c#. The programs mostly make operations on
the windows media server. They create publishing point, for example,
on the fly.

I had a look there. But no one that got the same king of problem.

I put log functions both in the php-script and in the c# app.

I restart the server, and everything works. But then, after may one
day, for some reason, one of the c# app (can be any of them) freezes
during the execution, and before it can returns.

The php-log says that, well, nothing. It stops when it has to show the
return value got from the c# app.

The C# app doesnt catch. That is the big problem. The log function in
the c# app is located at the end of the try statement. And exactly
before the return statement. In the log file I try to write the return
value. But it is blank, for some reason.

Worst of all, maybe, is that the c# app is runnable from the command
line. Always. And it executes returning the value. So the problem, as
I see it, is that suddenly the php-interpretor hangs up when running
exec.

Yes, this is obvious, as I created a dummy c# app, one that only
returns hello world. Well, after the php-interpretor (or is it apache
stuff?) hangs up, I cannot either get the return value from that app.

Is it an apache problem? What do you think guys? But the error log
doesnt have any trace of problems with the exec...
