i have the same issue with you, goroutine suddenly increasing to a million, this is involved with OOM

goroutine 9405091 [semacquire]: sync.runtime_SemacquireMutex(0xc000e5fd14, 0x0, 0x1) github.com/patrickmn/go-cache.(*janitor).Run(0xc000d646c0, 0xc000133140) created by github.com/patrickmn/go-cache.runJanitor
