Cisco 2821 stops accepting client vpn connections

Hi,

Have a cisco 2821running 12.4  (Cisco IOS Software, 2800 Software (C2800NM-ADVSECURITYK9-M), Version 12.4(3g), RELEASE SOFTWARE (fc2)   )   that stops responding to client vpn connection initiations after 5-6 weeks of run time. This unit terminates several site to site ipsec tunnels, and also has the 1 ipsec client vpn connection configured as well.

 I've read a few cisco release notes that indicate running a 'clear tcp tcb *' might fix this, instead of  having to reload. Is there a newer s/w release we should install? Or a fix for this issue?

Thanks

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
