Having an issue with CentOS 5.1 - after install there is a process called nash-hotplug that is running and consuming 100% of one of my CPU cores (QuadCore Xeon CPU). Seems to be a 'nice' process as it steps out of my way when other apps need all the CPU, but I am struggling to understand what it is. According to the manpage nash is a script interpreter, but that doesn't translate easily into what nash-hotplug would do.
A search around the usual places turned up a lot of people having this issue in Xen environments, but that doesn't apply to me, running standard CentOS 5.1 kernel 2.6.18-53.1.21.el5. The only "fix" I see is adding 'pkill -9 nash' to my /etc/rc.d/rc.local.
Anyone have some input on this?? What IS nash-hotplug and why is it there on a non-xen system?? I can't remove nash because of dependency issues - specifically mkinitrd!
-Thanks in advance for any help!

nash-hotplug is a script
nash-hotplug is a script interpreted by nash.
It loads basic kernel modules from initrd at startup,
mounts root fs ro and starts init process.
Try to upgrade (or maybe downgrade) nash.
nash..humph
It always annoyed me that Fedora/Redhat use their own home-cooked nash thing instead of just bash, because one has to put features into nash and recompile that instead of just using shell scripts and the appropriate tool (e.g. mdadm) like suse does.
