storeUpdateCopy: Aborted errors in 2.7

[Chris Woodfield <rekoil@xxxxxxxxxxxxx>]

Hi,

We're testing a migration from 2.6 to 2.7, primarily to get the HTTP/ 
1.1 header in squid-to-origin requests in a reverse proxy environment.

Per our test plan, we migrated one of two servers sitting behind a  
load balancer to 2.7STABLE3 with the patch for bug 2406 applied; that  
bugfix appears to be working as expected (thanks henrik!)

The particular servers we're testing with are reverse-proxying a well- 
known OSS mirror site, so the content load skews towards the large  
side. The two servers are running identical configs save for the  
http11 directive in the parent cache-peer statement on the 2.7 instance.

Getting to my point, we've been noticing the following errors on  
syslog on the 2.7 instance. We've never seen this before 2.7, so I was  
wondering what it means (I'm guessing it reports either a failure to  
save a cacheable object to disk, or to update headers on an already  
cached object?) and what the implications are.

Since we moved to 2.7 yesterday afternoon, this has shown up in the  
syslog 9 times.

Can someone take a look and let me know if this is safe to ignore? I'd  
be glad to run at a specific debug level if it will help.

Thanks,

-Chris
