We managed to get it tuned to the point where user complaints are 
minimal, but there is definitely still a problem.  We've also had 
Asterisk randomly die a few times.  Nothing is written to the logs in 
these cases.

Digium investigated the echo issue (over SSH) and claimed that my 
"system is handling several non-maskable interrupts" and that I should 
pull out the TE121 and watch /proc/interrupts.  I can't really pull a 
production system down for that kind of invasive testing, so we're just 
living with it at the moment.

If anyone knows of a particular server in which the TE121 is known to 
work *reliably*, I'd be much obliged.  We thought that a SuperMicro 
server would be a decent choice, but apparently that's not the case.
