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: Jan 20 18:23:42 ldap kernel: [5636879.604870] slapd invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0 Jan 20 18:23:42 ldap kernel: [5636879.604894] slapd
