メモリリーク - java.lang.NoClassDefFoundErrorが：COM/mchange/V2/RESOURCEPOOL/BasicResourcePool

2012-04-27 9 views

環境： サーバー：JBossの4.2.3.GAメモリリーク - java.lang.NoClassDefFoundErrorが：COM/mchange/V2/RESOURCEPOOL/BasicResourcePool

我々は、接続プーリングのためC3P0 0.9.1.2を使用しています。

ホットデプロイ Jboss ASのwarファイルにc3p0からのメモリリークが発生するたびに発生します。 最終的には"java.lang.OutOfMemoryError：PermGen space"になります。エラーが発生すると、アプリケーションサーバーを強制的に再起動します。

誰もこの問題に遭遇しましたか？この問題の回避策はありますか？

次のようにスタックトレースは次のとおりです。

Whenever we hot-deploy war files in Jboss AS are encountering the memory leak from c3p0.

あなたのJBoss 4.2でホットデプロイ（またはJBossの他のバージョン）の場合は、最終的にPermGenプールでメモリリークが発生し、サーバが必要になります再起動。私が知っている回避策はなく、c3p0とは関係ありません。

開発中、これはほんのちょっとした迷惑です。プロダクションでは、まったくやってはいけません。

誰かがそれについて何かする必要があります。しかし、それは長い議論です。 – Mindwin

私は誰もそれについて何もしないと信じています。私は今mongodbを使用していることをうれしく思っています。 – aspdeepak
