We’re running 5.2(5) and don’t seem to have any problems. It might be a link issue too. Check your interfaces and make sure they are hard set to 100full or whatever. Auto could have some issues with some switches. I would setup a syslog server on both PIX’s and capture the “Window” in debugging mode for Cisco’s TAC. Also, troubleshooting this LIVE with Cisco after you’ve done this might be required. If the problem persists don’t reboot the PIX and call the TAC team so you can troubleshoot it.
