[nsp] Re: 2621 keeps freezing

[Steve Rude]

Do you have CEF turned on?  CEF will drop CPU load significantly.

In your acl's do you have the log statement?  Every time you have a
packet hit the log statement, it will cause CPU cycles.  

Can you log into the router console when it freezes?

I have several 2621's with 4 T1's running about 3-4 Mbps peak in a
Multilink bundle, and relatively small acls and I've never had a problem
with freezing.  CPU runs about 40-60 percent at peak times.

I run 12.2(8)T10, you might want to give that a shot.
 
Good luck,

  That should have read "The load was high on the non-Internet T1
router, and it would seem to drop EIGRP hello's and cause adjacency
issues every now and then.. so I thought it might've been a memory
issue so I upgraded another 2621 and sent it out, but the old router
never froze up completely requiring a reset.. it would just get
slow."

  So yes, add EIGRP to the list of things this router is running as
well.
