Listner Corrupt cache

ok solved with Recreate listener cache

now slapd dies continuously i think there is corrupt mdb file:

slapcat > ucs.ldif

5f1b3ade The first database does not allow slapcat; using the first available one (2)
5f1b3adf ch_malloc of 10648517296 bytes failed
slapcat: …/…/…/…/servers/slapd/ch_malloc.c:57: ch_malloc: Assertion `0’ failed.
Aborted

how to repair the mdb file?

thnx a lot.
