Port Block Allocation Errors
Hi, I just want to know why I am getting the PBA -exhaust -alert every now and then. I have not configured PBA, and I am using One to One mapping NAT. Is this normal? thanks

For port exhaustion to happen even with just 1 public address you would need more than 64000 sessions alive at that time. I doubt that this is the case.
Nihas, can you tell how many sessions you see at maximum? Does it come close to >50K?
If not I bet this error is not really caused by the circumstances but rather by a bug in v5.0.5. I recommend to update to 5.0.9 soon to see if this has an influence.
