JAVAlang.OutOfMemoryError:内存不足

Question

我们在公司使用TIBCO integration manager已经有一段时间了，但几个月后，在这个过程中遇到了内存不足的问题，只有在重新启动时才会得到修复。下面是我们在日志中收到的错误

当前JVM设置为小于大小

JVM

java.extended.properties -Xms1024m -Xmx2048m

虚拟内存

$ulimit-d-v

data seg size (kbytes, -d) unlimited

virtual memory (kbytes, -v) 37748736

服务器上的内存

$free-g

             total      used       free     shared    buffers     cached

服务器操作系统：

已经尝试增加虚拟内存，也在配置中调整了JVM大小，但到目前为止没有任何帮助。 你能推荐其他的方法吗
