hi I think the question is "what are the specs of the machine on which acedb runs" more than the specs of your linux box (since it is only used as an xterm) since everything works for one user on the same machine, I believe the problem might come from some stack size or other limit, set in your distant shell eg, if your distant machine (the one running acedb) is a linux and you use bash on it, try the command ulimit -a you can try setting some values to unlimited (most probably the stack size: ulimit -s unlimited) if your distant shell is tcsh, the command is limit, check your tcsh manpage for details if it's some other shell I don't know, but there are generally analogues to these commands Well, i'm no acedb guru so it could be anything else, in that case someone else can perhaps help you hope this helps nicolas Chia Hung wrote: > Hi, AceDB gurus, > > I am currently using AceDB v. 4.9h on a Dell dual Xeon processor (I > Don't know the RAM size) running RedHat Linux 8 with Gnome window > manager/desktop manager.
