error after OS upgrade

[Greg Martin <gmartin@gmartin.org>]

I upgrade to Slackware 12 this weekend and now openldap won't start.  A 
google search didn't help me. I'm running 2.3.27.

I can restore from backup, just want to make sure that's necessary and 
maybe I can learn something in the process.

Errors from the tail end of ldap.log:

bdb(dc=gmartin,dc=org): unable to allocate memory for mutex; resize 
mutex region
bdb_db_open: Database cannot be opened, err 12. Restore from backup!
====> bdb_cache_release_all
bdb(dc=gmartin,dc=org): DB_ENV->lock_id_free interface requires an 
environment configured for the locking subsystem
bdb(dc=gmartin,dc=org): txn_checkpoint interface requires an environment 
configured for the transaction subsystem
bdb_db_close: txn_checkpoint failed: Invalid argument (22)

Thanks
