[Ovmsdev] Memory leak

[Michael Balzer]

Steve,

I've seen some allocations looking like memory leaks but getting freed after a minute or two. I assume those are mongoose buffers or LWIP socket
structs getting freed after some timeout.

But if I remember right, those were accounted for on the TCP/IP task and/or the NetManTask, not on dynamic tasks.

I start dynamic tasks primarily for web command execution in streaming mode. The "vfs tail" command also runs as a dynamic task.

If you had the mDNS component still active, that could also be the cause.

Regards,
Michael
