Dear Cyrille,
Yes my ldap process is getting disappear... I assume due to CPU/high search... because only that days I can see the CPU are getting increased... There is no crash information file for slapd Thanks, -Arun From: Maucci, Cyrille [mailto:[email protected]] Sent: Monday, July 25, 2011 6:19 PM To: Arun Sasi V (WI01 - Manage IT); [email protected] Subject: RE: SlapD is using more CPU Dear Arun, >> And also I just want to know why my ldap service are getting stopped.... What do you mean? Do you mean the ldap unix process disappears ? If so, did you enable core dumps to be written (ulimit -c) ? Do you get a core file ? I would not expect slapd to simply 'exit'.

I have configured Multi-Master setup here... i.e two location servers will act as multimaster and remaining 7 locations are act as slave servers(read only copy). Each location sync with master ldap and fetch the update from master Ldap (syncrepl)... My infra the number of users are accessing the LDAP more on Sundays hence Ldap server is utilizing more cpu on those days and getting hang... Please find the attached some report which I took from Ldap server. I have increased my cache size.. will it cause to high CPU ...? And also I just want to know why my ldap service are getting stopped....

( ! ). I must have misunderstood your statement. Since slapd is multi-threaded, I've myself pushed slapd to much more than 100% CPU. So what do you mean by 'slapd is getting stopped' ? Do you mean the process vanishes ? Does it leave a baby core file around there ? If so, you should probably send the back trace. ++Cyrille ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, July 25, 2011 9:55 AM To: [email protected] Subject: SlapD is using more CPU Hello Team, Whenever the number of search increase to the master server... slapd is utilizing more about more than 100%... What could be the reason and also is there any bench mark defined... Whenver it goes 100% slapd server is getting stopped...
