No data after running for some time

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run data-input.py debug v
2. check logfile for debug logging

I have an issue that after running, the grabber shows values in the 
webinterface, and also to pvoutput. After some time the grabber still runs but 
seems to stuck in a loop. Debug logging keeps updating but no data values. I 
have attached the logging.
The file shows output, which stopped around 15:00.

What version of the product are you using? On what operating system?
I used the latest revision, but 115 seems to be most stable

Running ubuntu 12.04 x64 with currentcost and 1 clamp.

I am confused....

Can you reproduce this or better asked happened it always at 15:00 or after a 
always same time period?

Does it happened only when you start it manual or did it happened also when you 
run it under supervise?

Greetings Thomas

Sorry to confuse you, Thomas!
Yes I can reproduce it. It happens on random times. Either when I start it at 
commandline 
$ python ./data-input.py or via supervise.

I now made a bash script that checks if the grabber is producing output, if not 
I restart the script. This is just a workaround.

The fact is that after running for a while, it seems to get stuck. The grabber 
still runs, but no power output. Only output you see is a hourly cron timer 
like this :

AND sensor=0
