問(wèn)題描述

我嘗試使用 1、2、3、4 GB 內(nèi)存啟動(dòng)該進(jìn)程，但仍然出現(xiàn)相同的錯(cuò)誤.有小費(fèi)嗎?gc 日志顯示它正在運(yùn)行 GC，即使它有足夠的內(nèi)存.但可能這個(gè)錯(cuò)誤與使用 NIO 的內(nèi)存映射文件有關(guān).有人以前見(jiàn)過(guò)這樣的事情嗎?如果是這樣，您是如何解決的?

I have tried starting the process with 1,2,3,4 GB of memory but still get the same error. Any tips? The gc log shows that its running the GC even though it has enough memory. But probably this error has something to do with the memory mapped files using NIO. Anybody has seen anything like this before? And if so, how did you solve it?
