Hi Team,
I have noticed that there are so many glusterfsd threads are running in my system and we observed some of those thread consuming more cpu. I did “strace” on two such threads (before
the problem disappeared by itself) and found that there is a continuous
activity like below:lstat("/opt/lvmdir/c2/brick/.glusterfs/e7/7d/e77d12b3-92f8-4dfe-9a7f-246e901cbdf1/002700/firewall_-J208482-4000025_20170126T113552+0000.log.gz", {st_mode=S_IFREG|0670, st_size=1995, ...}) = 0
lgetxattr("/opt/lvmdir/c2/brick/.glusterfs/e7/7d/e77d12b3-92f8-4dfe-9a7f-246e901cbdf1/002700/firewall_-J208482-4000025_20170126T113552+0000.log.gz", "trusted.bit-rot.bad-file", 0x3fff81f58550, 255) = -1 ENODATA (No data available)

I have found the below existing issue which is very similar to my scenario.
https://bugzilla.redhat.com/show_bug.cgi?id=1298258
https://bugzilla.redhat.com/show_bug.cgi?id=1298258
We are using the gluster-3.7.6 and it seems that the issue is fixed in 3.8.4 version.
Could you please let me know why it showing the number of above logs and reason behind it as it is not explained in the above bug.
Regards,
Abhishek
