I am experiencing a very similar issue on the C3750E platform w/ 12.2(52)SE.
We have 5 switches in a cluster, port-channeled with (2) Gig interfaces L2
to distro (6500's) with excessive output drops even at low utilization. No
QoS enabled. I am using the Cisco TwinGig Converter Modules for uplinks..
We have a TAC case open, but no progress yet. I'd be interested in knowing
if you find a cause. I am going to try swapping GBICs over the weekend.
3750s also have tiny buffers, so will suffer similar problems.
They are "LAN" switches, and as such Cisco deem it unnecessary for them
to actually pass traffic reliably!
