I have an OCEAN script in a BIG for-loop that submits many jobs - looks a bit like this: foreach( corner process foreach( vdd voltage foreach( ctemp temperature foreach( vicm list(0.05 0.5 0.85 1.3) foreach( prc par /* other stuff going on */ jobs=cons( run(?jobName job ?queue "hspice") jobs) ))))) It all works fine and the HSPICE Q has about six jobs running at any one time (jobs are short - two minutes)......BUT after a while (maybe 150 or so jobs) - the whole thing grinds nearly to a halt. I only see ONE job on the Q at any one time ???? Any ideas please.....at a complete loss. Thanks.
