Noticed that sometimes the device hangs/crashes and even the WDT does not get involved reboot. But we see messages from wifi:

Other times, an actual SO is produced. This happens more if we increase the taskdelay.
It looks like the tiT task is the lwip TCPIP task with a default stack size of 2048. Not sure if this needs an increase, but not sure if that's the root cause of the crash.

Am I doing something wrong?
