Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* I have pasted config.ldif
of my fedora-ds server in attachment.

You said its ran out of memory, but the next day morning
after fedora-ds was crashed, I checked cacti monitor of
memory, Â*memory and cpu usage rate was on a normal level ,
far from exhausted.
Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*
And after I restart fedora-ds server 2 hours without
changing any configuration, there was no response from ldap
server but the process was running and 389 port was
listened. And this time no errors were written into error
log. I had to restart it again and it have been working fine
from then on.

Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*
Do you have any idea of this?
Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*
Thank you for your advice.Â*Â*Â*Â*Â*Â*Â*
Not sure.Â* Looks like all of your cache settings are the default
values.Â* I suppose it could be a memory leak.
I suggest upgrading to 389 1.2.7.5 available from EPEL.Â* Even if
that does not solve your problem, it will be much easier to support.

Hi all,
Â*Â*Â*Â*Â*Â*Â*Â*Â* Fedora-ds was down for some
reason,
Â*Â*Â*Â*Â*Â*Â*Â*Â* And Â*I Â*got these logs:
Â*

The server has probably allocated all
available virtual memory. To solve
this problem, make more virtual memory
available to your server, or reduce
one or more of the following server
configuration settings:
Â* nsslapd-cachesizeÂ*Â*Â*Â*Â*Â*Â* (Database
Settings - Maximum entries in cache)
Â* nsslapd-cachememsizeÂ*Â*Â*Â* (Database
Settings - Memory available for cache)
Â* nsslapd-dbcachesizeÂ*Â*Â*Â*Â* (LDBM Plug-in
Settings - Maximum cache size)
Â* nsslapd-import-cachesize (LDBM Plug-in
Settings - Import cache size).
Can't recover; calling exit(1).
Â*
Â*
Â*
Â*Â*Â*Â*Â* It looks like no more available
virtual memory to use, so should I set a lager
nsslapd-dbcachesize?
Â*Â*Â*Â*Â* I don't know if it will down again,
and please give me some advice . its important to me. Thanks a
lot
What version
of fedora-ds or 389-ds-base?
What platform?
This usually means you have run out of memory.Â* The usual
thing is to reduce your cache sizes (as specified above).Â*
Start with nsslapd-dbcachesize as the minimum.Â* Set
nsslapd-cachememsize to be large enough to cache all of your
entries, but no larger.
