Kevin,
Thanks for the answer. My setup is a little more complicated than that. The sensor reads its configuration from the server. The server could reconfigure the sensor between restarts.
I did try stopping the task graph and restarting but the problem is unresolved. I tried ulocking but I get the following: AttributeError: 'top_block_sptr' object has no attribute '_unlock'
Regards,
Ranga

You must ensure that the old block is destroyed.
In order to do this, you must of course drop all references to it within your program, but you must also remove it from the GR flow graph and, if the graph is running, _unlock() the graph_ before creating the new block.
But:

Instead of recreating the source, why not recreate the connection to the server and keep the source?
