Well, the servers are running for a long time, not only a days. I have done that search, but the "Entry cache hit ratio" remains 0. I have also noticed that "Current entry cache size (in entries)" is only 4168, even after the search, although out directory cointains about 50000 entries. Is this normal?

until entries get into the cache and are pulled from the cache rather
than the database.
Try doing a search like ldapsearch ... -b "basesuffixofdatabase"
"objectclass=*"
