All of these are cache corruption issues. I can't seem to reproduce them locally.
Are you running the latest SVN ? There was a bug in the SVN version of ATS a little while ago for a couple days before it got fixed. Did you clear the cache before running (start with traffic_server -K)? Changes in the cache format are supposed to be tracked by versioning of the database, but there might have been a change which wasn't accompanied by a version bump. If can provide access to a gdb session with the crash I might be able to figure out what is going on... john On 9/20/2010 6:20 PM, Pranav Desai wrote: > On Thu, Sep 16, 2010 at 3:30 PM, Pranav Desai <[email protected]> wrote: >> On Thu, Sep 16, 2010 at 2:03 PM, Leif Hedstrom <[email protected]> wrote: >>> On 09/16/2010 02:45 PM, Pranav Desai wrote: >>> >>> On Thu, Sep 16, 2010 at 12:33 PM, Leif Hedstrom <[email protected]> wrote: >>> >>> On 09/16/2010 01:26 PM, Pranav Desai wrote: >>> >>> Hi! >>> >>> I am running a load test with some video files to see .
