PHP Version: 4.1.2
New Comment:
The same with:
system("exec $DLC/bin/_mprshut $CADB/$DB -C watchdog 2>&1
</dev/null");
This _mprshut needs no input.
(I mail this problem also to the developer of _mprshut,Progress
Database.)
The rest of the php script finishes but i can't open a new page and
have to close this session.
In the moment i have no further idea to separate this command from the
actual www session.
I tried "at", that works but +1 minute is too late. :-(

system("exec $DLC/bin/_mprshut $CADB/$DB -C watchdog 2>&1
</dev/null");

Hi,
system("exec $DLC/bin/_mprshut $CADB/$DB -C watchdog 1>/dev/null 2>&1
&");
has the same effect!
_mprshut is a daemon that ended in a second.
Please notice: The script doesn't hungs the rest works fine after
system.
I can't open any new page after accessing this script an
_mprshut listen on port 80.
On HP-UX the Apache still works fine with a listening
_mprshut.

Hmm, on second thoughts, it sounds like your OS is broken.
Does the equivalent script written in perl do the same?

Please read the docs about system().
System executes the process and waits for it to complete
before returning.
You need to append an & character to your command to cause
it to run in the background.

This are my simple commands:
system("$DLC/bin/proserve $CADB/$DB 2>&1");
system("exec $DLC/bin/_mprshut $CADB/$DB -C watchdog 2>&1");
The first command works fine but the second hangs the actual httpd
session.
It executes o.k. but tries to get the actual webserver process:
[root@linux datenbank]# lsof | grep www
httpd 30824 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30825 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30826 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30827 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30828 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30829 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30831 root 16u IPv4 28772 TCP *:www
(LISTEN)
httpd 30835 root 16u IPv4 28772 TCP *:www
(LISTEN)
_mprshut 31169 root 16u IPv4 28772 TCP *:www
(LISTEN)
This process is the parent of 1:
[root@linux datenbank]# ps -ef | grep 31169
root 31169 1 0 13:14 ? 00:00:00
/home/dlc83e/bin/_mprshut /home/
[root@linux datenbank]# ps -ef | grep 30835
root 30835 30824 0 10:59 ? 00:00:00
/usr/local/apache/bin/httpd
Then my actual session of my IE hangs and i only can lose it.
The php script is ended because i got </body> and the IE loading bar
vanished.
I can't restart the server because this process 31169 holds port 80
open.
I use the same script on SCO, Reliant Unix and HP-UX11.
On HP-UX11 the _mprshut also listen on port 80 but on a different
session because the website still reacts.
The apache server restart is impossible before killing this process
manually.
Any ideas where i can search the problem ??
