Tom,
For logging, I do this:
OVMS# vfs cat /store/events/sd.mounted/logging
log file
log file /sd/ovms.log
log level verbose
log level info ssh
Seems to work well. It won’t catch system level output (like crashes), but at least shows what our apps are up to.
We don’t know the order things happened (no logs), but Steven’s module tasks stack is working well and gives lots of clues as to the cause. Many thanks.
Looking at Blk tiT (reverse order):

It seems that the ppp link went down, and that triggered a GsmPPPOS_StatusCallback. That in turn called pppapi_connect to reconnect. That went into the tcp_api_call.
I am concerned that we are doing a tcpip_api_call from within the tiT thread. The LWIP PPP library has two versions of each call. One seems to be intended to be called from within the tiT thread, and the other dispatches the call (via a freeRTOS queue) to be executed from within the tIT thread. But, that logic comes straight from the LWIP PPP examples, so I’m really not sure what is going on.
Looking at GsmPPPOS_StatusCallback, there are a bunch of error codes that can come into that, and they all result in a call to pppapi_connect except for PPPERR_NONE and PPPERR_USER. The actual call we make is pppapi_connect(pcb, 30), which should delay the reconnection for 30 seconds.

So here we have a ticker.* signal being issued by housekeeping (in Tmr Svc context, because this code pre-dates the switch yesterday to run these in housekeeping task context). Looking at simcom, that must be ticker.1 because that is the only ticker.* that simcom hooks into. That must be a normal state ticker (State1Ticker), and ends up with a pppapi_close. No idea what state we were in at the time.
The pppapi_close is only called in one place from simcom ppp (GsmPPPOS::Shutdown). That can in turn only be called from the main simcom as a result of the last good frame timeout.
The last few frames of this stack show the tcpip_api_call being raised, and that calling sys_arch_sem_wait to wait for the response from the api call (in the tiT task context). I think the 0x4008b981 xQueueGenericReceive is garbage and shouldn’t be in the backtrace.
The way lwip works is that there is a tIT thread that runs the main IP stack. Function there are not intended to be called directly (from other threads), as they may not be thread safe. So, instead, the tcpip_api_call is used to create a structure packing the call details, and push that structure onto a queue. The tiT thread then reads that queue, executes the function in it’s own context, fills in the result, and then signals completion. The original caller is waiting (sys_arch_sem_wait) for the signal from tiT that that call is complete, and then regains control (in it’s own stack) to handle the result.
I don’t see any real problems in Tmr Svc. There is a hell of a lot going on in a timer call, but we’ve already addressed the core issue there (that Michael identified yesterday), and with current code this part will now run in housekeeping context. Anyway, I don’t think this is the issue.
More concerning is the behaviour in the tIT task. I’m guessing the sys_arch_mbox_fetch followed by pppos_disconnect is our call from Tmr Svc for pppapi_close. So we’ve got an incoming queue message there, and we are handling it (with the sender task Tmr Svc waiting on sys_arch_sem_wait for the signal the function has completed executing in the tiT task). LWIP then calls the status callback (to tell it about the link down), and our code (running in tIT task context) calls pppapi_connect to reconnect. That schedules a pppapi_do_ppp_connect to be run in the tIT task and waits for the semaphore to be set to indicate it is done. But, we are already in the tiT task, so we never look at the incoming function call queue, so we block forever.
Bottom line: I think the fix is to directly call the internal ppp_connect function (as the callback is in tiT task context), rather than scheduling an inter-task call (pppapi_connect):

That was a lot of work, and a lot of hassle, for three lousy characters. The LWIP example for PPPoS uses ppp_connect (not pppapi_connect).

@Tom: can you try it?
Regards, Mark.
Tom,
This seems clear, and about what I expected. Looks like the timer service is in 'pppapi_close’, and the tcp/ip task is in ‘pppapi_connect’. One is trying to connect, the other disconnect, and they are deadlocked.
I think the '0x400eec76: OvmsCommandApp::Log’ in Blk tiT is a false report - can’t see how that is called from there.
I’ve got to put some time into ‘day job’ now, but will have a look at it in detail later.
Regards, Mark

I've got it hung up at the moment. Unfortunately it was during the one drive where I didn't use the datalogger so I don't have the logs leading up to the hang.
Time is still advancing, but monotonic is not. I don't have it connected to the idf monitor so addr2line is a bit tricky.
