Errors on VAM2 VPN module

Hello,


I have a Cisco 7301 VPN router with VAM2 module connected to a 50 Mbit Internet line.

This router connects the remote offices to the Headquater using GRE-in-IPSec VPN tunnels (currently

about 25 tunnels using Transport mode, AES encryption, COMP-LZS compression).


If there is a high traffic, I get a high amount of errors and drops in "sho crypto engine accelerator statistic 1":


ppq full errors : 123961

pkts dropped : 123961


What could be the problem?

Is this a performance problem of the VAM2?

Is there a way to tune/debug the VAM2?


Best regards,

Chris
