crypto errors CTM ERROR: Failed to allocate x bytes of memory

Hi There.

I am currently getting a strange error when trying to use and crypto services on our ASA 5520 (8.0.3)

Initially I observed that a connected VPN had dropped.

Then when I attempted to use ASDM or SSH I was blocked.

In the end I opened telnet as a test and this was successful. Syslog also shows that traffic is passing as normal.

The only obvious error I can see when observing various debug traces is this;

FW02# CTM: rsa session with no priority allocated @ 0xCF1FBBA0

CTM: Session 0xCF1FBBA0 uses a nlite (Nitrox Lite) as its hardware engine

CTM: rsa context allocated for session 0xCF1FBBA0

CTM: rsa session with no priority allocated @ 0xCE7A5EA8

CTM: Session 0xCE7A5EA8 uses a nlite (Nitrox Lite) as its hardware engine

CTM: rsa context allocated for session 0xCE7A5EA8

CTM: dh session with no priority allocated @ 0xCEF249D0

CTM: Session 0xCEF249D0 uses a nlite (Nitrox Lite) as its hardware engine

CTM: dh context allocated for session 0xCEF249D0

CTM ERROR: Failed to allocate 279 bytes of memory, ctm_nlite_generate_dh_key_pair:183

Has anyone seen anything like this before as I am lost?

Mike
