[ERROR] [STREAMER] The receive packet handler caught a value exception. B210

[elmaghba]

Issue Description

In my basic flowgraph, I have a USRP source that is connected to a head block to control the capturing time. Then, the head is connected to two different low-pass filters which each one of them is connected to a file sink block. The low-pass filters have the same sample rate as the USRP source block. When I run the flowgraph, it prints some zeros in the terminal, then, it gives me the following error:

USRP Source Block caught rx error code: 15 [ERROR] [STREAMER] The receive packet handler caught a value exception. ValueError: bad vrt header or packet fragment

Setup Details

I'm running the gnuradio/uhd on a VM virtual box-Linux Ubuntu 18. USRP B210

Expected Behavior

I captured the data for 4 devices, then, it stopped working!

Actual Behaviour

Prints (00000000000000000000), then: USRP Source Block caught rx error code: 15 [ERROR] [STREAMER] The receive packet handler caught a value exception. ValueError: bad vrt header or packet fragment

I'm still getting the same issue. If there is any further information I need to provide, please let me know!

Any help is really appreciated!

@elmaghba Can you try this outside of a VM? We have often heard about USB issues when running in virtualbox. Also, can you post a flow graph here that exhibits the issue? And which UHD version were you using?

I'm still getting the same issue. If there is any further information I need to provide, please let me know! @mbr0wn I use 4.2.0.1 UHD version

I am running eNB and it starts correctly, works well. Then out of nowhere, the error pops up and my eNB is dead.
