YPServ uses a lot of CPU, why?

[MANEL Rodero (LCFIB Systems Analyst)]

Hello,

Sometimes 'ypserv' uses a lot of CPU in our Samba machine. Here is a 
capture of the output:

load averages:  7.11,  4.71,  4.18

15165 root      44    0 6568K  745K sleep   0:00  1.60% smbd 

Any idea about what's happenning? Other servers running Samba doesn't 
have this problem? (OS = Digital Unix, Samba = 2.0.6). Note: 2.0.7pre3 
has the same problem.
