Allocation failure in Java
提问by dumper
I have a method which hits DB and fetches lot of records into memory for processing. After I fetch the records and before I start processing, I get the following log message. What does it mean ?
我有一种方法可以访问数据库并将大量记录提取到内存中进行处理。在获取记录之后和开始处理之前，我收到以下日志消息。这是什么意思 ？
164575.034: [GC (Allocation Failure) 4937664K->3619624K(5602816K), 0.0338580 secs]

It just basically tells you that it had to run GC to allocate additional memory, it does not fit in memory otherwise. So it is just a reason for GC.
它只是告诉你它必须运行 GC 来分配额外的内存，否则它不适合内存。所以这只是GC的一个原因。
