Slow and Crashing on Raspberry Pi

Hi all,

(Duplicate here as I’m unsure how to proceed)
I’m having problems running mitmproxy successfully on my raspberry pi.
I’ve set it up this way such that I can find a certain requests which can appear randomly, however I’ve found that if I keep mitm continuously proxing, the requests seem to become slower and slower, until it just dies.
Just recently after getting the request I was searching for, by the time I got to the web client to view the logs, it had crashed and everything disappeared.

Is there something I’m overlooking?
