jvm - Websphere ヒープ サイズ 4GB。それぞれが 3 GB のメモリを並行して消費する 2 つのスレッドを実行しているヒープをメモリが超えるか、それとも websphere が 1 つのスレッドを一時停止しますか?

Question

あいまいで申し訳ありませんが、Websphere のメモリ管理を高レベルで理解しようとしているだけです。

Answer 1

This is really a question about JVM behavior. As far as I know, there are no JVMs that will block a thread waiting for another thread to finish if it is holding a large amount of memory. I expect both threads to continuously consume memory, and if both are able to allocate memory at the same rate, I would expect them both to get OutOfMemoryError as soon as their combined allocations exceed the max heap size.
