I guess this also is very hard to recover from? (other than clear and start all over)

Can you also share a crash log (via serial port) ?

This issue seems no longer relevant, and can be closed.

I've looked at the SSDP code a few times and it for sure is a memory allocation issue as we need to allocate quite large packets of data.
Not sure if we can 'stream' the data as you probably need to know the exact size of the message in advance.
