Jack Bates commented on TS-1528:
--------------------------------
Thank you very much for your support James Peach, and for the support I
received in IRC. Traffic Server is running on a dedicated EeeBox B202 machine,
with an Intel Atom N270 processor (32-bit) and 1 GB of RAM
Thanks a lot for these improved log messages. I haven't yet had a chance to
re-test master, but expect they will make it much easier to understand problems
like this in future. I will re-test and post the output
With help on IRC, I was able to avoid this integer overflow by increasing
proxy.config.cache.min_average_object_size to 16K, but when I started Traffic
Server, the system load average would climb because Traffic Server used all
available memory, and eventually segfaulted. I set
proxy.config.cache.ram_cache.size to zero and increased
proxy.config.cache.min_average_object_size until it used less than all
available memory. It's been running okay for about a week now, with
proxy.config.cache.ram_cache.size zero and
proxy.config.cache.min_average_object_size 64K
I'm now experimenting with re-enabling a 256M RAM cache

> Issue Type: Bug
> Affects Versions: 3.2.0
> Environment: Debian testing (wheezy) on i686
> Reporter: Jack Bates
> Assignee: James Peach
>
> I consistently get the following error whenever I try to start Traffic Server
> (release 3.2.0). Yesterday I built Traffic Server from Git HEAD (34a2ba) to
> check if it behaves any differently, but I consistently reproduce this same
> error whenever I try to start it, too
> Here's my configuration, which is pretty minimal:
> http://nottheoilrig.com/trafficserver/201210120/
> What details can I provide to help debug this? James Peach suggested
> attaching some kind of dump of the volume header:
