Memory Leak Caused by Using Go STL to Query DB
Problem Origin Recently, a Go API service was found to have continuously increasing memory usage through regular monitoring. The memory usage rose from the initial 70MB to over 1GB until it ran out of memory and crashed. This clearly indicated a memory leak issue.
