DAtabase out of locker entries

[Jorge Izquierdo <jizquierdo@sgi.es>]

Hi everybody. I asked a week ago for some problems with the lockers of 
the Berkeley Database running my openldap version 2.1.17.

Somebody suggested me to upgrade to 2.1.21 version because the 17 had 
some database problems. I have upgraded but I still have the same 
problem. After two days running my server, I get next error in the 
openldap log:

Jul  2 14:13:41 <HOSTNAME> slapd[7259]: [ID 446079 local4.debug] 
bdb(<SUFFIX>): Lock table is out of available locker entries

I´ve searched on the lists and I´ve found that there was a bug in 
BerkeleyDB version 4.0 about the behaviour of the database with locker 
entries. The problem is that I´m using Berkeley 4.1.25 and it seems this 
bug is corrected in this version.

Can anybody show me the way to find a solution to this problem? Why the 
database gets off of locker entries? How may I fix a higher value of the 
 posible number of lockers and lock entries?

Thanks for any ideas.

Jorge
