DS DB index out of sync-poor performance

DS is observed slower search response time on Solaris 10U3 compared to Windows. The cache size is the same on the two boxes, even though it should be bigger on solaris (windows is 32bit, solaris is 64).

This search for example shows different etimes consistently :

On Windows the search took 0.079000 seconds :

[19/Oct/2007:15:33:41 +0200] conn=2062529 op=1 msgId=2 - SRCH base="ou=qp_na02,ou=apps,ou=internal,o=ericsson" scope=2 filter="(&(objectClass=groupOfUniqueNames)(uniqueMember=UID=XBMVIVI,OU=Partners,OU=External,O=ericsson))" attrs="cn"

[19/Oct/2007:15:33:42 +0200] conn=2062529 op=1 msgId=2 - RESULT err=0 tag=101 nentries=114 etime=0.079000

however this same search took 0.320350 seconds on solaris :

[19/Oct/2007:17:02:30 +0200] conn=460 op=1 msgId=2 - SRCH base="ou=qp_na02,ou=apps,ou=internal,o=ericsson" scope=2 filter="(&(objectClass=groupOfUniqueNames)(uniqueMember=UID=XBMVIVI,OU=Partners,OU=External,O=ericsson))" attrs="cn"

In the solaris errors logs, i see lines like this "candidate not found" :

it looks like the index is out of sync.
