Hi,

I need some assistance please.
I've taken over an IPA server to manage a few months ago, and it was
working fine until recently when it started acting up seemingly off its own
accord.
When I do an ipactl status it basically gives an output as shown below:



*Directory Service: RUNNING*

*Loooooooooooooooooooooooooooooooooooooooooooooooooong pause... (To the
tune of 7 minutes sometimes)*

*KDC Service: RUNNING*
*KPASSWD Service: RUNNING*
*DNS Service: RUNNING*
*MEMCACHE Service: RUNNING*
*HTTP Service: RUNNING*
*CA Service: RUNNING*
*ADTRUST Service: RUNNING*
*EXTID Service: RUNNING*

Running top showed that ns-slapd was munching almost all my resources, but
I got that fixed by upping the cache. Unfortunately this did not correct
the issue and it still reacts in the same fashion, although the resources
have been freed up now.
I've noticed that when I run dig on either the local server or a remote
machine that the query basically just times out as shown here:

 *dig freeipa.myexample.sample*

*; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>>
freeipa.myexample.sample*
*;; global options: +cmd*
*;; connection timed out; no servers could be reached*

When the KDC service fails to start, then name lookups seem OK, but
authentication fails. otherwise it's dead in the water.

This also happens:

*sudo ipactl status*
*Directory Service: RUNNING*
*Unknown error when retrieving list of services from LDAP:*

My software setup is as follows:


*CentOS release 6.5 (Final)*

*389-ds-base.x86_64   1.2.11.15-34.el6_5*

*bind.x86_64          32:9.8.2-0.23.rc1.el6_5.1*
*bind-dyndb-ldap.x86_64*
*bind-libs.x86_64     32:9.8.2-0.23.rc1.el6_5.1*
*bind-utils.x86_64    32:9.8.2-0.23.rc1.el6_5.1*
*rpcbind.x86_64       0.2.0-11.el6
@anaconda-CentOS-201311291202.x86_64/6.5*
*samba4-winbind.x86_64*

*krb5-server.x86_64   1.10.3-15.el6_5.1*


*Linux 2.6.32-431.29.2.el6.x86_64 #1 SMP Tue Sep 9 21:36:05 UTC 2014 x86_64
x86_64 x86_64 GNU/Linux*

It's not a permanent situation as it sometimes runs 100% for a while, but
80% of the time it is unusable. If anybody can assist me, please be so kind.

Regards,

Walter
