Performance on Solaris 7 SPARC (ITS#1511)

Full_Name: Siu Tabo
Version: 2.0.15
OS: Solaris 7 SPARC

We use OpenLDAP-2.0.15 to authenticate web logon users from an oracle database
server 8.1.5 on the same network using DBPool Connection in Tomcat-3.2.3. 
It runs fine at the first few days, but then it sometimes makes the loading of
the web server (with solaris7 on e450 with dual cpu) so high that it reaches 32
almost 2 to 3 times a day.  Each high loading period lasts for few minutes.  We
use top to see it and we found that the slapd uses utmost 97% of CPU time. 

We checked the logs and we didn't find any special problem.  During the high
loading minutes, the web service is normal and authentication seems no error. 
Just simply the web server's loading is extremely high. We tried the same
environment on linux and it doesn't give high loading. 

Please give us some hints in any way, thanks so much!
