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

Key: TS-473
URL: https://issues.apache.org/jira/browse/TS-473
Project: Traffic Server
Issue Type: Bug
Components: Cache, Configuration
Affects Versions: 2.0.1
Environment: Fedora 12 kernel version 2.6.31.5-127.fc12.x86_64
Intel Core i7 920 2.67 GHz
12 GB DDR3 1066MHz
Traffic Server version 2.0.1 (Stable)
Reporter: Devin Madden
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 cant provide any other configurations or logs one would
need so feel free to ask!
Thanks,
