[jira] Commented: (TS-473) Traffic Server keeps crashing the
kernel. I have a feeling it has to do with an incorrect cache
configuration.
[ https://issues.apache.org/jira/browse/TS-473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12921003#action_12921003 ]
Leif Hedstrom commented on TS-473:
----------------------------------
Is there any chance you can try v2.1.3 and see if this problem persists? The changes from v2.0 to v2.1.3 are enormous, and the v2.1 branch is the base for our next stable release, v2.2.

> 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
> Attachments: records.config, storage.config

> 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.
