      Catching a few MangoGT units hanging, to find Out Of Memory errors in the logs:

      Suggestions? Adjust thread pools? Swap?

        Was this ever fixed?

        Do not follow where the path may lead; go instead where there is no path.

          Either get more memory or try this env property:

          #Set the number of files the database can have open at one time
db.nosql.maxOpenFiles=500

          It will close/unmap files at the expense of cpu use. If this problem persists then try another stream type:

          #Query Performance Tuning, File Access Type:Available[INPUT_STREAM,FILE_CHANNEL,RANDOM_ACCESS_FILE,MAPPED_BYTE_BUFFER]

db.nosql.shardStreamType=MAPPED_BYTE_BUFFER
