strange performance of ASA 5510

10 days ago I installed ASA 5510 at a site. I was using image 7.0 (2). Static translations on a DMZ interface didn't work (I know PIX OS very well so this is not due to misconfiguration ) while dynamic translations worked. I upgraded to 7.0(4) and faced some very strange problems:

- Most of the time the command sh run hangs the ssh session, so I have to open another one.

- Sometimes write memory doesn't work, warning that 'configuration is in progress', while nobody is configuring it.

- The strangest of all is that sometimes the internal subnet is being messed up and computers are not able to communicate with each other. The LAN has no problems, as another firewall works without any problems. Re-placing the old firewall (it's not from Cisco) solves all the above mentioned problems.

Has anyone any experience with this equipment. What I'm not sure whether these are due to software bugs or some hardware malfunction.

I'll apprecieate any help
