Re: OS X Server Directory Service (?) unresponsive



Got similar problems. Our OD master just clags up. It's a G5 running 10.4.10. Static IP. No DNS runningon it. No DHCP running on it. No NAT running on it. Just OD as a master, and Samba as a PDC.

I have been ssh-ed in to the server before it clags up and run "top - o cpu". What I see is that "Password Server" is flogging itself to death - it does this periodically, and sometimes it drags LDAP with it. Both processes alone take up pretty much 100% of the CPU, and that is when the server is basically a boat anchor.

I'd love to have this not happen, as re-booting it to fix the problem is less than ideal.

In our case, the OD server is set up w/ static IP addresses, however, it does supply DHCP and NAT services to our LAN. It's also running DNS services and VPN (which supplies DHCP for VPN clients).

Am I understanding correctly that any one or any combination of these things could cause Directory Services to cease up as they all could and do cause network events?

Possibly, but they shouldn't. A greater consideration is the load on each/all of the services. How many OD users and why not have your Router do NAT and DHCP ? You should find it's been frequently discussed on this list, that even a cheapo, "home"-style router is going to do just as good a job if not better.


If you stand back a minute and think of this not from the point of view of "my Mac can do it, so why not," and rather, look at it in terms of overall system & network architecture, then you arrive at a different mindset. Just because a server /can/ do certain jobs (NAT & DHCP), doesn't mean it should or that it's even best that it does - in fact it's probably better that it not.

It absolutely can, the question is do you want it to (see above) ?
