process to be killed by the system. I have initially investigated, Severe memory leak hdrStrHeap and hdrHeap 9814933504 | 9814794240 | 2048 | memory/hdrStrHeap 9814933504 | 9814859776 | 2048 | memory/hdrHeap I sincerely ask your: how to solve the problem of memory leak? Thanks everyone! yongshou.wang 2/5/2018
