Uncommon but nasty data corruption

Andy Knipp

OD 731 on Linux. We noticed files being corrupt when we pushed blocks of content from test to production in anticipation of go live. We also noticed it got worse as we changed the bufferSize because of WAN latency.

After some tests we narrowed it down to only happening with TeamSite to TeamSite transfers with extended attributes transfer on. The real break came when someone examined the corruption and determined it always happens starting at byte 4097 which is one page plus 1

Using a bufferSize that is a multiple of 4096 prevented any corruption.

Working with support it appears the root cause is an known issue with UVFS version 2.0.5. We have not upgraded because we have a workaround and we do not want to go through the testing required.

Anyway thought I would post this in case others hit this issue
