[TS-473] Traffic Server keeps crashing the kernel. I have a feeling it has to do with an incorrect cache configuration.

Description

I am attempting to set up a mini network at my place of work to do some testing with Traffic Server. The command I used to configure traffic server was this:

./configure --enable-webui --with-user=dmadden --with-group=dmadden

I followed the directions to set up the cache before the first boot up of the server. I originally wanted to just use a file on my local hard drive. When I tried this however it corrupted my Fedora installation beyond the capability of fsck. I then tried to use a blank hard disk for the cache. In storage.config, I added the line:

/dev/sda 85899345920

This would hopefully create a 80 GB cache on the disk. I start up traffic server and it seems to start up OK. But then the ABRT starts telling me I have a crash in the kernel package. This is the relevant portion of my /var/log/messages file:

I don't know how to attach the storage.config and records.config files, and posting the text here would take way to much room.

So basically, what am I doing wrong? Any feedback anyone could give me would be highly appreciated. I can provide any other configurations or logs one would need so feel free to ask!

EDIT: For what it's worth I am trying to use the Traffic Server in forward proxy mode.

Thanks,
