Description Peter Portante 2013-02-06 21:07:34 UTC 
When the Gluster/Swift object-server code detects that a given file does not have an etag value (md5sum() of the data in the file), it will generate the etag in-line when generating new metadata. For large files, this can be time consuming, and thus the other requests currently being handled by that object-server thread can be starved.
Comment 2 Kaleb KEITHLEY 2015-10-22 15:46:38 UTC 
because of the large number of bugs filed against mainline version\ is ambiguous and about to be removed as a choice.

If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
