Gateway crash

[GoogleCodeExporter]

What steps will reproduce the problem?
1. 3 devices are using XIG / HTTP
2. Changed config file, 1 setting:   global_max_buf_size = 512
3. Communications have been fine, but occasionally 1 of the 3 devices will 
eventually stop being able to communicate (device does show up on the network 
via the X4 interface)
4. This is the first crash - I have been restarting XIG to get the 3rd device 
working.  It usually works for about 18 hours before stopping.

What is the expected output? What do you see instead?

What version of the product are you using?
v1.4.1 of XIG on a ConnectPort X4

Please provide any additional information below.

Unsure of the 3rd device issue is related to the crash...

Thank you for reporting the issue.  It looks like the HTTP server you are 
communicating to, or the connection to your HTTP server, is timing out 
mid-response.  Neither Python's httplib or the XIG code have been "robustified" 
against these cases.

Was this a one time occurrence or are you able to reproduce this fairly easily?

This has only happened a single time.  I'm currently testing the system with 3 
devices transmitting about 250 bytes every 2 seconds to our servers through XIG.

Thank you for reporting the issue! We likely wouldn't have caught this one if 
you hadn't reported it.

Would you mind testing this beta for us?  It catches the exception, closes the 
socket, and reports the error to the XBee rather than crashing the XIG.  Which, 
I believe, is a preferable behavior :)

Sure, uploading it to our test site right now.

This is mark @ clear blue, btw. :)

it immediately crashes on my X2.  

XBee Internet Gateway (XIG) v1.4.2b1 starting.
Unzipping and loading modules...
Traceback (most recent call last):
  File "<string>", line 35, in ?

Will try my X4...

Same error on the X4

Haven't been able to get this version to run due to the missing 'library' file, 
and have had another crash since my last report.  Any idea when there will be a 
version for me to try that works ?

Here is a second beta to try.

Please find attached a beta 3 which adds a global exception handler.  You may 
still see connection exceptions (for valid errors such as the BadStatusLine 
exception) but the XIG won't crash.

It looks like this failure has been resolved. I'm going to release xig-1.4.2. 
Thanks for testing!
