Here is a patch based on ESP8266_NONOS_SDK_V1.3.0 (non-OS SDK) resolved issue that if there are 2 connections, one is normal TCP connection, the other is SSL connection, it may cause memory leak.
Download and unzip the attachment, replace the lib in esp_iot_sdk/lib folder.
Please do not set the same priority for two different tasks when using system_os_task.
Sorry for the inconvenience.
更新附件 lib，基于 ESP8266_NONOS_SDK_V1.3.0，解决当普通 TCP 连接和 SSL 连接同时应用时，可能存在的内存泄露问题。
请将附件替换到 esp_iot_sdk/lib 路径下。
注意: 调用 system_os_task 建立任务时，不同任务的优先级必须不同，请勿将两个不同的任务创建为同一优先级！
给您带来不便，深感抱歉！
