"cannot create communication semaphore" - Error



We recently re-installed SAP and done a database recovery on my R3 system. We are running SAP 6.40 with MAXDB

This is running on Linux.

My problem is since the recovery i get this message on my system log as well as when trying to use MaxDB gui "cannot create communication semaphore" if i stopsap, then i can access the database via the gui without a problem but once SAP is running i cannot access the database to do backups or add volumes.
