g98l problems

I think it's a shared memory issue (+Linda library missing). You should 
increase the maximum shared memory segment for instance:
echo 134217728 >/proc/sys/kernel/shmmax (depending on the total physical 
ram you have)
You also can add it in the /etc/sysctl.conf so that it does it at every 
reboot).
Do you use Linda for the "parallel" library? If so you have to put 
NProcL in your .com file...otherwise I don't know how you can get g98l 
work without it.
Hope this helps.
