STATUS_NOMEM on SiLabs EFR32 #2372
Description
Hi there,
I've been testing SiLabs MGM12P modules with OpenThread. After a 30min to 2 hours of operation the NCP stops transmitting/receiving IPv6 packets. On every transmit wpantund tells me that NCPs last status is STATUS_NOMEM.
Nov 27 23:35:49 wpantund[399]: Tickle...

Has anyone else encountered this before?
What's the best way to debug this when it takes several hours to reproduce?
