We have got the same problem here, exec hangs sometimes and causes the
page to not respond to anything. Only way is to restart apache. Is there
a solution available for this ?

Dear markus

In the first sight, I also understand that this happen only when
multiple request hit the script with exec(). But in reality there is no
guarantee that if the request goes one by one Hanging will not happen. I
had done a test at the time of writing this bug in which call the script
one by one but it randomly hanged up again after a period of time. At
that time period is long.

So dear PHP team , you have to really look up this matter.

Thanks

I have the same problem. 

I noticed that apache only hangs up when a php script with an exec
command was called twice at the same time.

The problem also ocours when I tried to use popen or proc_open(with and
without bypass_shell option)

Executing resource kit utility shortcut.exe via exec() with EXACTLY the
same results...  Random, no errors logged, hangs up all succeeding calls
to exec(), requires restart.

Dear Jani

There is no problem with 'sample.exe'. I have tested the same for
different exe or even for dos command. It hangs when we are calling the
page at regular interval of time (through Ajax).

There is a problem in the definition of exec() function.

For any further information , feel free to contact me.

What exactly does this "sample.exe" do? It's most likely not any PHP
problem at all anyway, you just call some exe that "hangs" itself..
