Hello All,
I am running a transmitter on an e310_sg1, uhd_4.3. that transmits for a
few seconds and repeats at a given interval continuously. Unfortunately I
can not share the code for the transmitter.
Eventually the e310 gets into a state that can not be corrected without
rebooting.
The errors below occur when querying sensors during this state.
[ERROR] [MPM.RPCServer] Uncaught exception in method set_device_id:
'NoneType' object has no attribute 'set_device_id'
Traceback (most recent call last):

Error: RuntimeError: Error during RPC call to `set_device_id'. Error

It appears the MPM is not released correctly at some point and can not be
claimed again.
I am hoping someone has seen this before and can recommend a way to avoid
this from occurring or at least recover without rebooting.
Thank you
