After a power failure a P166 with 32M RAM/1.6G IDE HD which worked fine for months running large quantum chemistry calculations ( avg 30M of memory and ~500M of scratch files) started to panic allways when l401.exe (one of the quantum chem calculations packages)is running: (this is a hand made copy) Idelazil Cristina do Nasciment said: > From ide@fluorescence.iqm.unicamp.br Wed Oct 9 16:22:04 1996 > From: Idelazil Cristina do Nasciment <ide@IQM.Unicamp.BR> > Subject: mensagem de erro > To: vazquez@fluorescence.iqm.unicamp.br (Pedro A.

Without running l401.exe the system stays up forever. Any ideas? Thanks Pedro
