Hi,

when I run slapindex with my mdb backend the data.mdb files grows and grows and when the configured maxsize (100GB) is reached it stops with cannot allocate memory. 50505d1e => mdb_idl_insert_keys: c_put id failed: Cannot allocate memory (12) 50505d1e => mdb_tool_entry_reindex: txn_aborted! err=80

To test, I created a very basic config. See below. Created a test ldif file with the LDIFGen.jar with 100000 DNs. The file is 110MB.

In the slapd.conf is only 1 index configured. uid with eq,sub. When I load this file with slapadd the data.mdb file gets 268MB. (Without any configured index 220MB) When I then run a slapindex, the data.mdb grows to 20GB.

If I add 2 more attributes to index. data.mdb gets 36GB index givenname eq,sub index sn eq,sub

My question is, is this normal? Why does the data file get's so big with a slapindex and not with a slapadd? OpenLDAP version is 2.4.32 on CentOS6 64bit.
