我们处理图像以从中提取各种功能。为此，我们提前调整图像大小。每当我们使用单个线程在离线过程中处理图像时，我们从未遇到过任何问题。但是当我们尝试处理多线程时，JVM崩溃不一致。
最大的问题是在同一组10K图像上，它会在崩溃之前处理整个集合几（2-3）次，而且我们使用-Xmx选项提供的内存越多，它就越有可能崩溃... （例如：12 GB在崩溃之前可能是30K图像，在16GB图像中它会在3-4张图像中崩溃）。 Server是30GB n 8 Core机器......
监控“top”显示虽然我们已经给出了-Xmx24g，但是当发生崩溃时内存使用量仅为20GB，所以我认为它与内存没有任何关系......
如果有人能给我一些关于问题可能是什么的见解，那么最感激。我认为它与线程有关，但我不知道是什么：（
