Hello all,
I'm experiencing some problems with some OpenLDAP servers: the slapd process seems to always use more memory, eventually reaching a point where it has consumed all the available server memory and is killed by the OOM killer. The servers have 32gb of memory plus 32gb of swap space and are running Debian Lenny (with kernel 2.6.26-2-amd64), and we have compiled OpenLDAP 2.4.23 from source, and we're using Berkeley DB 4.6. The servers are dedicated to running OpenLDAP, so they don't have other processes that use a significant amount of memory.
This is a relatively high-volume environment, with 4 servers running with mirrormode to enable multi-master replication. The current database size is about 900mb. Is there any setting that could limit this memory usage? I don't feel this is "normal" considering our DB size and cache sizes.
Very likely ITS#6660, you need to update to 2.4.24.
