Hi Sebastian,

what about fixing this bug instead of using this workaround? This sounds 
really inefficient.

I don't think there is a hard limit. Do you see any errors (e.g. memory 
allocation issues) in the server logs? Another idea, if you're somehow stuck 
to the old/ buggy version of the server, what about using DB_ONLY mode?
