[unclug] Unstable RedHat 9 machine

I have an unstable RedHat 9 machine acting as my department's primary 
mail server and DNS server.  Obviously, having this machine crash on a 
*weekly* basis is unacceptable, and I'm at my wits end trying to figure 
this one out.  I notice that while no log shows any kinds of errors 
(that I can find that is), the console occasionally shows this error: 
"svc: short len 2, dropping request".  Suffice it to say, I have no idea 
what this means, and Google didn't help.  Does anyone have any idea 
where I should start, or something specific to look for?  I can say that 
all this instability seems to have started (though I can be 100% sure) 
with the replacement of the hard drive after a HD failure.  However, I 
have run hdparm with numerous options trying to rule out hardware 
problems, and I haven't seen any errors thus far.  I am running the 
latest kernel before RedHat moved to EL.  Thanks for any light you can 
shed on this!
