Hi Neto,



I'm using the Default access specification.  I changed the transfer
request size to 4 KB, but dynamo is still hanging when the test stops.



Thanks,



Eric





Additional info:  when the tests are running, the only results that get
updated on the Results Display tab is CPU Utilization.  All of the other
results are 0.



I rebuilt dynamo with  _DEBUG and _DETAILS=1.  Here is the output:

Please try to change the block size to 4096 bytes and do the test.



Thank you



All the best

Subject: [Iometer-user] Dynamo gets stuck at the end of testing



Hello,



I'm looking for help with a problem I'm having running IoMeter.  The
problem is that dynamo seems to hang when the first test completes.
Here is the output:



Command line parameter(s):

  Looking for Iometer on "10.221.220.20"

  New manager name is "taylor"



Sending login request...

  taylor

  10.221.220.49 (port 38153)

*** If dynamo and iometer hangs here, please make sure

*** you use a correct -m <manager_computer_name> that

*** can ping from iometer machine. use IP if need.

  Login accepted.

At this stage the IoMeter GUI is also frozen.



Here is the configuration I am using: 



IoMeter version 1.1.0-rc1 (iometer-1.1.0-rc1-src.tar.bz2)

IoMeter GUI is running on Windows XP. 

Dynamo is running on a linux box. Built dynamo in the linux test
environment.  (make -f Makefile-linux.i386 all)



Thanks,



Eric
