I have two PIX 515's running in failover mode that were just upgraded to ver 8.03 from v 7.11.
Ever since the upgrade on Friday the PIX will work fine for about 10-15 hours. Then all of a sudden no one on my network can send mail? I have confirmed that when this happens my mail server (sitting on the outside of my network - so mail passes outbound on the PIX before getting to the mail server) does not see the attempt to send the email as it is not getting past the PIX.
The only thing that seems to get it going is a reset of the FW's.
Any ideas would be great.
