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

Question

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: 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?

Thanks for that. It does look like its out of crypto memory...
DMA memory:
   Unused memory:                 23849516 bytes (30%)
   Crypto reserved memory:        20537556 bytes (26%)
     Crypto free:                       0 bytes ( 0%)
     Crypto used:                20537556 bytes (26%)
   Block reserved memory:         34669024 bytes (44%)
     Block free:                 30734752 bytes (39%)
     Block used:                  3934272 bytes ( 5%)
   Used memory:                     185120 bytes ( 0%)
Unless there is a way to specifically restart only the crypto engine or clear crypto memory then I guess I am looking at a reload?
