Check with top & iotop the load.Especially check the wait for I/O in top.
Did you check dmesg for any clues ?

Hi Strahil,
 
I poked around our logs, and found this on the front-end (from the day & time of the last time we had the issue)
 

 
 
Jun 15 10:51:17 mseas gdata[155485]: [2022-06-15 14:51:17.263858] C [rpc-clnt-ping.c:165:rpc_clnt_ping_timer_expired] 0-data-volume-client-2: server 172.16.1.113:49153 has not responded in the last 42 seconds, disconnecting.
 
 

 
 
This would indicate that the problem is related.  For us, however, I believe we can reproduce this issue at will (i.e. simply try to gunzip the same file). Unfortunately I have to go to a meeting now, but if you have some specific tests you'd like me to try, I can try them when I get back.
 
Thanks
 
Pat

 Pat,  
   Can you check the cpu and disk  performance when the volume reports the issue? 
   
  It seems that similar issue was reportedin https://lists.gluster.org/pipermail/gluster-users/2019-March/035944.html but I don't see a clear solution. Take a look in the thread and check if it matches your symptoms.

Hi Strahil,
 
I poked around again and for brick 3 (where the file we were testing resides)  I only found the same log file as was at the bottom of my first Email:

      I agree. It will be very hard to debug. 
  Anything in the brick logs ? 
  I think it's pointless to mention that EL6 is dead and Gluster v3 is so old that it's worth considering a migration to a newer setup.
