Currently running Samba-3.0.5 but when upgrade to Samba-3.0.8,9 or 10 the messages.tdb grows until the servers memory and swap is exhausted. The server is running RedHat 7.3 and has Samba configured as a Print server. Comunication between the Server and Printers is via LPRNG. Currently there are 45 printers shared on the server.
fixed in 3.0.11pre1. Backported patch for 3.0.10 available at http://samba.org/~jerry/patches/post-3.0.10/
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
