Looks like the file exists:

# ls -alh 
-rw-r--r-- 1 dirsrv dirsrv 0 Mar  9 09:39

We did a systemctl restart ipa.. which failed.. but looks like the dirsrv is 
still running. The logs are now filling up with:

[09/Mar/2016:10:23:10 -0500] DSRetroclPlugin - delete_changerecord: could not 
delete change record 11272988 (rc: 32)
[09/Mar/2016:10:23:10 -0500] DSRetroclPlugin - delete_changerecord: could not 
delete change record 11272989 (rc: 32)
[09/Mar/2016:10:23:10 -0500] DSRetroclPlugin - delete_changerecord: could not 
delete change record 11272990 (rc: 32)

However, if I do a kinit:

kinit: Cannot contact any KDC for realm 'CBLS.CCR.BUFFALO.EDU' while getting 
initial credentials

Should I be concerned that this will end up corrupting the other replicas? 
Should we just let this finish?

We have 3 replicas in our system. Looks like we just lost a second one. This
feels very similar to the error we hit a while back:


We're seeing the exact same behavior.. access logs are filling up with:

The ns-slapd proccess is showing this from top:

24951 dirsrv    20   0 15.477g 0.013t 6.067g S   0.0 27.3 101566:54 ns-slapd

I'd be happy to provide a pstack but can't seem to get the correct debuginfo
packages installed.. we're running centos7 and  389-ds-base We haven't
upgraded to How can I get the debuginfo packages installed for that
specific version.
