Weblogic服务器 OutOfMemory error 请高手指点迷津 或给一些参考线索

Question

4台linux 集群 ，gslb
jvm初始内存设置为Xms 2G Xms 2G 
经过一段时间的调查，内存应该是足够的，应该从配置或是代码方面着手。
错误信息：

希望对你有帮助

Answer 2

我们的环境如果有select检索结果特别多，会造成这种情况。对应方法就是重启server，然后改需求，给select加条件

Answer 3

请问楼主这问题解决了？
我这也有这个趋势，com.octetstring.vde.syntax.DirectoryString占用的内存很多

Answer 4

楼主。问题后来怎么解决的啊。我这边也遇到这个问题了，可否指点一二啊？[email protected]  这是我邮箱，希望得到协助  谢谢。
