i just installed WebMo an tested it a litle,

as long as only one job (g98) is running everything is fine. If the second job is started, the job finishing first kill files from the other
job so that it crashes. I asume as only one g98 at a time is reasonable, the second one should be queued, but this does not happen.

what went wrong ?

It sounds like WebMO is starting a second copy of the daemon that controls the running of jobs. This would normally only occur when WebMO incorrectly thinks that the daemon is not already running. This most likely indicates an error in the parsing of your process information.

After examing output from your "ps" command, I found the following:

root         1     0  0 Apr27 ?        00:00:05 init [5] 
root         2     1  0 Apr27 ?        00:00:00 [keventd]
root         3     1 11 Apr27 ?        2-16:06:26 [kapm-idled]
root         4     1  0 Apr27 ?        00:05:08 [kswapd]

The line marked in red is strangely formated(because of the large cpu-time), thus causing the process information to be parsed incorrectly.

To fix the problem, edit the file globals.int, located in the <webmo>/cgi-bin/interfaces directory so the the appropriate line reads:

psRegExp="(\$pid, \$ppid, \$cpu_time) = /.{7}(.{7})(.{6}).{3}.{6}.{6}(.{12}).*/"

Note: The above regular expression is accurate for most Linux machines. Normally, the appropriate regular expression is automatically and correctly determined at setup time.
