KRB5_REALM_CANT_RESOLVE errors ?

[Christopher Burke]

My application which authenticates to K5 (1 thread at a time) gets KRB5
_REALM_CANT_RESOLVE errors alot when it (the application) is under a high 
load.

Once it starts getting them it gives that error for all attempts until the 
load reduces dramatically.

Any hints on exactly what the error means and what may be causing it ?
