[Ovmsdev] Stack overflow: What is task "itT"?

[Mark Webb-Johnson]

I think that is the TCP/IP task. Maybe CONFIG_TCPIP_TASK_STACK_SIZE?

Have a look in menuconfig and see what you have those stack sizes set to (/STACK to show them all). A ‘module tasks’ can show you the current running values. My tiT is 3072bytes in size (but max level is 696 bytes).

CONFIG_TCPIP_TASK_STACK_SIZE=2560

Regards, Mark
