Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

I am using TI-RTOS  V2.16 for TM4C1294NCPDT microcontroller. Application has web-server which uses NDK from TI-RTOS. 

I was keep getting "TcpTimeoutRexmt: Retransmit Timeout" error. So I increase all stacks as shown below.

NDK: 2048(orignally) to 10240
Low priority task: 2048 to 4096
high priority task: 2048 to 4096
med priority task: 2048 to 4096
Task default stack: 512 to 4096
idel task stack: : 2048 to 4096
Program stack: 2048 to 4096

After running over the weekend with debugger attached I am still getting "out of memory" and "TcpTimeoutRexmt: Retransmit Timeout" errors.

 

Please console events and ROV screen-shot for Task->Detail below.
