Server responds with different ids

[d84812]

Today I faced with a weird behavior with doipclient + udsoncan library, after connection is established, my app sends data identifier requests, but receives replies to the other ones. This is related to the only one DOIP server.

Seems like some garbage on rx buffer. I managed this by deleting Ethernet adapter and reinstalling it. But after 5-10 minutes it happened again. No antivirus SW on that PC.

Example: requested f186, but received db94, etc.

What is going on there? Any ideas?
