problems with ypserv + rmmod

I don't quite understand this, but here is the problem:
Server and all clients run rh7.0 + all updates.
From time to time ypserve starts spanning children until it reaches its
The load will go up to 30 and the sever will not react for about a minute.
After that everything is fine again.
Inspecting the log shows that this happens always after rmmod is executed
Jan 16 11:30:01 keen CROND: (root) CMD ( /sbin/rmmod -as)
Jan 16 11:31:01 keen ypserv: WARNING(ypproc_all_2_svc): too many
A "ps" shows:
626 ? D 2:04 ypserv
642 ? S 0:00 [ypbind]
646 ? S 0:03 [ypbind]
647 ? S 0:00 [ypbind]
651 ? S 0:02 [ypbind]
28643 ? D 0:00 ypserv
28678 ? D 0:00 ypserv
It does not happen every time rrmod is executed. In addition, it is not

system. I have removed the kmod entry form cron.d and it hasn't occured
I don't see how this "rmmod" can directly be a problem for ypserv. Are you
some limit for the number of processes on this machine?
If you still have logfiles pointing at the real problem we run into here, please
a new bug-report with more information. It might be that ypserv should have
checks for error returns, but I need more information on what exactly is going
Thaks for this report.
