Problem Description

I use BearSSL::WiFiClientSecure client to build a MQTT client and a HTTPS client in my project, it will stuck some time when the client connect to server url, but the codes may not Abort called at once.I set a ticker run every 3s to test, when the codes stuck, the ticker may run a long time. I rewrite the BasicHTTPSClient to descrip this bug, when the freeheap is low the tcp client or http client will stuck. But the WDT or softWDT still run for a minutes or a long time.

Thanks You removed your logs that were useful, even more if you decode the (removed) stack trace and also enable OOM(OutOfMemory) debug option before running your sketch.

Thanks, I think the logs not same as I descrip, so I removed it. I will enable OOM debug and hope will get more useful logs.

@d-a-v Hi, dear d-a-v, I update the example codes, this codes can stuck and will not Abort called for a long time(may hous or days). Excuse me, is there some way to avoid stuck when there is low heap? I have set a function like below codes, but it will stuck some times. And with different version codes, the compare heaps is different.

if (ESP.getFreeHeap() < 4000) return;
