High CPU usage on disconnection of device

[pglira]

I'm using a ublox neo-m8u device. I observed that when the connection gets lost (e.g. disconnection of the usb cable), the CPU usage of all cores immediately increases to 60-80%. See here two screenshots before and after removing the usb cable:

Error message is:

[ERROR] [1576242406.425972302]: U-Blox ASIO input buffer read error: End of file, 0

Is this a known problem?
