Hello, openldap-technical@ readers.
I'm running openSUSE 11.4 with openldap 2.4.23 and libdb-4_8
(berkeleydb) in vmware environment.
Last friday my slapd was killed by oom killer. Seems that it consumed
all available memory. It is
the first time i see that openldap was killed.
My database is rather small (15953 entries, 22 mb on disk id2entry.bdb
+ dn2id.bdb).
Could somebody point me to place where i can limit memory usage in openldap?
Here is part of log:
