Problems with ping dropped packets

The only thing I can glean from this setup is the trunk links between Po27 & SW6FA4-Internet1....   Could the ping traffic that's experiencing drops be hashed to a particular link in the port channel? *** Do during maintenance window *** if possible, disable one link between gtm1 & SW6FA4-Internet1.  monitor ping loss, restore then disable the other link.  You could have the traffic hashed onto one of the links in the port channel and its possible a bad patch.
