IPSEC ESP Bad Pad Length

I have a PIX 501 with 3DES using the EZVPN in network extension mode to a 3005 VPN concentrator. The concentrator is logging this error from the PIX. Can anyone tell me what this is, and should I be woried?

This is bug CSCea08566, nothing to worry about. You can check it in Bug Toolkit here:

Re: IPSEC ESP Bad Pad Length

Is it certain that this is nothing to worry about? I get an _awful_ lot of them. The bug seems to be an open caveat - it says duplicate of CSCdz33769, which says resolved in 6.3.1.

I have 6.3.1 and still see an awful lot of these messages. Does the duplicate being fixed mean the former is also fixed?

And we are having problems with our VB SQL app used by our PIX 501 clients tunnelling through our 3030 to a SQL server here. We wonder if this message indicates anything useful?

If this message truly is irrelevant, how can I turn it's severity down so it stops cluttering the logs?
