[MooseFS-Users] mfsmaster memory usage

[Wilson, S. M <st...@pu...>]

?Hi,


I've noticed that the mfsmaster daemon doesn't seem to relinquish memory once it has allocated it for metadata.  We occasionally will have a spike in the number of files in a MooseFS file system which will drive the memory usage up on the mfsmaster server.  But when the spike is over, the memory is not released by mfsmaster.  Last week, for example, we had one server that jumped up to more than 200 million files but it normally only has around 100 million.  So mfsmaster is still holding onto 69GiB of memory and will only release it if I restart mfsmaster, which is never convenient to do.


Would freeing up unused memory in mfsmaster be something difficult to implement?  If it's not too difficult, it should be worth consideration.


Thanks,

Steve
