Hello

I have a strange issue with OpenLDAP configured by iRedMail installation.
After the setup finishes, I am able to restart the jail and connect to every web interface, create users, connect to port 25 etc etc.
But after stopping and starting the jail again, I'm getting the slapd issue above.

I'm new to bdb, so if this is not the right place, please direct me to some different list, anyway it happened second time.
At first, I was thinking that I made some mistake during install, so I reinstalled iRedMail, but it happened again.
When I install OpenLdap separately in another jail, I have no issues.

Seems to me like BDB issue, but I don't know how to resize the mustex region (if needed) or restore the db from backup.

Thank you

P.
