             Summary: Truncated objects in the cache
                 Key: TS-4221
                 URL: https://issues.apache.org/jira/browse/TS-4221
             Project: Traffic Server
          Issue Type: Bug
          Components: Cache
            Reporter: Leif Hedstrom


After upgrading to v6.1.x, we see a fair amount of these warnings:

{code}

{code}

It's happening across the border on all boxes upgraded to 6.1. We're not seeing any (or many) of these on the 5.3.x machines. According to Plevyak, this is indicative of bad writes, possibly broken connections. What's odd in our case is that we only see this on our child caches, the parents (running 6.1) do not see this at all.
