Hello, Pranith. The typical behavior is that the %cpu on a glusterfsd process jumps to number of processor cores available (800% or 1200%, depending on the pair of nodes involved) and the load average on the machine goes very high (~20). The volume's heal statistics output shows that it is crawling one of the bricks and trying to heal, but this crawl hangs and never seems to finish.
The number of files in the xattrop directory varies over time, so I ran a wc -l as you requested periodically for some time and then started including a datestamped list of the files that were in the xattrops directory on each brick to see which were persistent. All bricks had files in the xattrop folder, so all results are attached. Please let me know if there is anything else I can provide.
