The maximum number of file descriptors can be tuned using max_files_per_process, however the more concurrent operations you do, the higher the risk to run out of them. Hence limiting them for short-time operations it preferred to keep things stable. You actually never need to hold them that long anyway, and you may want to rethink what you are doing as well. -- Michael
