7206VXR w/VPN module - dead sessions - is there a limit?

Hi all: I'm hoping someone here can help me. We have two Cisco 7206VXRs with VPN modules, upgraded G1 processors & 512 mb of memory each.

We have an intermittent problem with a handful of users getting connected successfully, but unable to access resources on our network. There is no obvious problem on the Cisco box or with the internet or our internal network. Out of about 900 sessions, only about 4 or 5 random users have this problem. Everyone else is fine. The only workaround we have is to move these affected users to our other 7206 VPN box. They come right up and are fine again.

I can't find any documentation suggesting possible causes for this - OR any that identifies the max number of sessions that these boxes can tolerate.

Does anyone know what the max number of sessions on these boxes are? Is 900 too many for our configuration?

Any help would be greatly appreciated.

Thank you -
