The kernel upgrade didn't help either.  I ended up rebuilding the tcltk 
src.rpm for Red Hat 7.2 with the suggested one line patch, and that seems 
to have solved the telnet hanging problem.

Now I have another odd one that I hope isn't a FAQ.  I've added a bunch of 
cisco access-servers (5200's, 5300's, and a 5800) to my rancid setup, and 
for some reason, these ciscos seem to vary the number of !'s separating 
sections of the config from one 'write term' to the next even though 
nobody has logged in and made changes to the config.

So I'm constantly being emailed diffs like:

  ip classless
  ip route 0.0.0.0 0.0.0.0 209.208.16.1
  no ip http server
  !
+ !
  access-list 20 permit ...
  access-list 20 permit ...
  access-list 20 permit ...
  access-list 20 deny   any

followed by  

  ip classless
  ip route 0.0.0.0 0.0.0.0 209.208.16.1
  no ip http server
  !
- !
  access-list 20 permit ...
  access-list 20 permit ...
  access-list 20 permit ...
  access-list 20 deny   any

Obviously, this would appear to be more of a cisco problem than a rancid
one, but I suspect someone else must have run into this and wonder if 
anyone's come up with a fix or knows how to get the cisco's to stop doing 
this.
