看堆栈是在解析网络包的时候踩内存了，但不知道具体是哪个变量导致的，bt full也没有打印具体值。如果有稳定复现的场景的话，麻烦提供下，我们这边复现下。
你们也可以在这些地方加一些日志或者assert。

According to the stack, the memory was touched when parsing the network packet, but I don’t know which variable caused it, and bt full did not print the specific value. If there is a scene that can be reproduced stably, please provide it and we can reproduce it here.
You can also add some logs or asserts in these places.
