CPU was still in the 70’s. Logconv.pl output looks much the same.
Follows.

----- Recommendations -----
1. You have unindexed searches, this can be caused from a search on
an unindexed attribute, or your returned results exceeded the
allidsthreshold. Unindexed searches are not recommended. To refuse
unindexed searches, switch 'nsslapd-require-index' to 'on' under your
database entry (e.g. cn=UserRoot,cn=ldbm database,cn=plugins,cn=config).
2. You have unindexed components, this can be caused from a search
on an unindexed attribute, or your returned results exceeded the
allidsthreshold. Unindexed components are not recommended. To refuse
unindexed searches, switch 'nsslapd-require-index' to 'on' under your
database entry (e.g. cn=UserRoot,cn=ldbm database,cn=plugins,cn=config).
3. You have a significant difference between binds and unbinds. You
may want to investigate this difference.
4. You have a high number of Directory Manager binds. The Directory
Manager account should only be used under certain circumstances.
Avoid using this account for client applications.
Cleaning up temp files...
Done.

Hi Mark,
Oops – sorry about the Mike thing! I sit beside a Mike :p
|No worries :-)
So your high CPU is most likely coming from your unindexed searches.
The version you are on should support the new per index
idlistscanlimit, so try this:
Note, this this is just an example, your objectclass entry might have
a different DN (userRoot might be something else in your deployment)
ldapmodify ...
dn: cn=objectclass,cn=index,cn=userRoot,cn=ldbm
database,cn=plugins,cn=config
changetype: modify
replace: nsIndexIDListScanLimit
nsIndexIDListScanLimit: limit=-1 type=eq values=inetOrgPerson
Depending on your results we might tweak the nsIndexIDListScanLimit
value again. This change should take effect immediately - no need to
restart.
Let me know how it goes.
Thanks,
Mark||

Oh – no notes in that search, but there are notes in the preceding
and subsequent searches. It looks like it returns the first 100
results then searches for groupOfNames for each of those users, and
then repeats until all 30,000 users is done:

----- Recommendations -----
1. You have unindexed searches, this can be caused from a search on
an unindexed attribute, or your returned results exceeded the
allidsthreshold. Unindexed searches are not recommended. To refuse
unindexed searches, switch 'nsslapd-require-index' to 'on' under your
database entry (e.g. cn=UserRoot,cn=ldbm database,cn=plugins,cn=config).
2. You have unindexed components, this can be caused from a search
on an unindexed attribute, or your returned results exceeded the

Done.

Hi Mike,
It's Mark :-) I get that a lot for some reason.
Thanks for the reply. The typical result of the result is:
[08/Dec/2014:07:08:04 -0800] conn=130262 op=1 RESULT err=0 tag=101
nentries=5 etime=0
Yeah this looks fine.
There are no notes=A/notes=U in the results.
Do you mean in the entire access log, or just for that search?
Can you run logconv.pl and post the results? "logconv.pl -V <access
logs>"
Thanks Trevor,
Mark
Objectclass and member are both indexed.
There were 30,000-odd searches on conn=130262, which took 34 mins.
Thanks,
Trev

Hi Everyone,
We’ve inherited a 389-ds system (1.2.11.15-48.el6_6) that is
running on a VM provisioned with a single CPU. We have been
experiencing high CPU with a client that connects with a single
connection, and then runs large amounts of queries of the form:
SRCH base="ou=GROUPS,dc=<our dc>" scope=2
filter="(&(objectClass=groupOfNames)(member=uid=<loginname>,ou=EMPLOYEES,<our
dc>))" attrs=“1.1"
Trevor,
From the access log, what is the result of this search? etime? It
there a notes=U/notes=A in the result? It could be an unindexed
search which would cause the high CPU.
Thanks,
Mark
We’re wondering if adding extra CPU’s to the vm will make things
better. The original engineer noted that at the time of
implementation, he had come across some notes that indicated that
the underlying process was single threaded and adding extra CPU’s
would not make any improvement; in fact, on heavily loaded vm
infrastructure like ours, may make things worse as the the vm would
have to wait for the CPU to become available. Is this still true?
Thanks a lot,
Trev
