Olio hangs close to end

[William Voorsluys <wi...@gmail.com>]

Hello,

I've been facing a problem that prevents me from submitting several
runs in a row. The PHP benchmark hangs and the last message that
appears in the log is:

INFO 	Transferring webserver error logs

The only solution in this case is restarting the master. Only killing
the current run doesn't solve the problem, as the next pending run
doesn't start.

I'm running the latest version of Olio, downloaded from the SVN on Apr
19 and Faban Kit 032009.

Cheers,

William.

I can't tell without more information. But perhaps a stack trace of the 
Faban master (tomcat) process using jstack will help us identify why it 
is hung there. This is certainly not the same as what you have seen and 
had to remove runs from the queue manually. BTW, does that still happen?

Are there lots of errors in these runs causing the error log processing 
to perhaps get confused/choked ? You could try changing the loglevel (in 
~faban/config/logging.properties) to FINE to see if you can gain any 
further insight into where exactly the problem is occuring.

I have run into situations where the master doesn't pick up the next run 
in the queue for some reason. But usually for me, the problem doesn't 
get solved by restarting the master either. I have to manually remove 
the run from the queue.

Akara - any insights into what might be happening here ?
