slapd memory usage



Hi.

I'm a bit worry about that slapd will use all of the memory
and kernel kills it violently (=> database corruption etc)
It seems slapd is reserving 1.6G of memory.
ldif dump of whole database is 84 megabytes of disk.
At this time there is 340 TCP connections to server.
Is this normal for slapd-2.1.30?
If it is we just have to buy more RAM :)

For backend we use bdb without DB_CONFIG (for defaults)

slapd.conf
...
threads 25
checkpoint 128 15
sizelimit 1000000
cachesize 90000
...
