Subject TS 2.0.1 and 2.1.3-unstable not for production environments?
Date Fri, 15 Oct 2010 12:23:10 GMT
Hi,

(sorry for bad english below, I will try my best).

I have tested TS 2.0.1 und 2.1.3-unstable as a reverse proxy on our
download platform a few weeks. We have a 10 GBit/s Uplink for all our
services and use 0,8 GBit/s in a traffic peak at the moment with our
download platform. At christmas season we expect a peak with 2,5
GBit/s.

The features and performance of TS are excellent, but the stability of
the software is the problem in my opinion. I hope more stability in the
next versions of TS.

At the moment I've the following problems:

TS 2.0.1
--------
This version crashes one time or more every day. The watchdog-system
correct this problem in a few seconds, so the service isn't offline, but
the actual download-sessions interrupt and in some cases it corrupt the
cache, so broken Files are sent to the customers. The last issue exist
at long the cache refresh from Origin-Server.

Crash-Logfile (traffic.out):

TS 2.1.3-unstable
-----------------
I know, that this version is a developer-version (unstable), but
because of the crashed of 2.0.1 I try this version.
This version have a problem with 206-requests (Partial Content). It
don't work with IE 8.0 for example. If click a download-url for a file
in a website via IE 8.0, the IE 8.0 download a few KB's (something like
300 KByte)  immediately (with Code 200) and after you have choose the
location for the file, IE try to get the last KB's with Code 206. This
produce an error in IE (like can't download the file). Most of
206-requests are logs with 1 Byte in the logfile (which causes an
error).
This problem don't exist in 2.0.1.

Logfile (extend2.log):

[... more thousand of log-entries ...]


Developer-Team: If you need more input (configs): contact me, please.


At the moment I see no stable version of Traffic Server.

What about 2.0.0? Is this a stable version without problems?



Best regards,
