Failed to start task #151

Closed herobrine30396 closed 11 months ago

herobrine30396 commented 11 months ago

I keep getting this error in the serial monitor, and the AsyncTcpWebserver doesn't work:

E [      5.316] failed to start task
E [      5.316] failed to start task
E [      5.316] failed to start task

It's a problem with the memory allocation of AsyncTcpWebserver. I created a fork that decreases the memory allocated to the library, and now it works!

I have another problem now. There's some issue that stops LwIPUDP::beginMulticast so that I get this in the serial monitor: E [ 5.322] could not join igmp: 125. Any help?

Yes, the task failing to start is nearly always because of lack of memory. I don't know which library are you using, but LT's fork adds another #define that decreases the stack size of the task. About the IGMP issue, check the errno codes for code 125. From a quick look in Google it might be "too many links" or "cancelled".

I recently ran into the same issue, and the problem appears lwip wasn't fully initialized yet. I added a delay before attempting beginMulticast (in this case, waiting until esphome's setup function had completed instead of just waiting for network::is_connected()), and it worked fine afterwards.

Oh, okay. Will try that, but right now, I'm not able to upload anything to my board to test it. I've created a separate issue regarding that
