Meghna and Kevin, Kevin made a great point. You need to have that flash upgrade. AND you need to make sure that who ever installed the 16 MB flash upgrade removed the old 2 MB flash card. The reboot cycle is a symptom of both these conditions. In order to stop the reboot cycles just put a boot disk for the previous version of PIX OS (in your case I think that's 5.1) in the floppy drive and power cycle the PIX. And I agree with Kevin's assessment. The read me docs caution that you should follow an upgrade path but I too have upgraded from 4.4 directly to later 5.2 and 5.3 software.
