Yeah, stack size is 2560. Tried bumping it to 4k, and that fixed
it. Backing down, it seems like just bumping it from 2560 to 2816
is sufficient to prevent the crash.<br class="">
<br class="">
What value should I set it to?<br class="">

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

<div class="">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).</div>

<div class="">Hi folks,<br class="">
<br class="">
I just updated to the latest (7 commits), and am having
trouble with a<br class="">
stack overflow in a task named "tiT". Not sure if
that's real, or if<br class="">
the task name has been corrupted.<br class="">
<br class="">
My startup script enables both simcom and wifi. Turning
off wifi<br class="">
doesn't prevent the crash. Turning off simcom does (I
get all the way<br class="">
to the server connecting), so it's apparently somehow
related to the<br class="">
modem and ppp stack.<br class="">
<br class="">
Thoughts?<br class="">
