ZipException or IOException on Linux for Java
Hu Dennis 2010-07-27
今天看到下面一段话：
When using a large number of file descriptors to load different instances of classes, you might see an error message "java.util.zip.ZipException: error in opening zip file", or some other form of IOException advising that a file could not be opened. The solution is to increase the provision for file descriptors, using the ulimit command. To find the urrent limit for open files, use the command:
ulimit -a
To allow more open files, use the command:
ulimit -n 8196
让联想到几个月前遇到的一个小问题，当时不知道这个错误是什么原因，或者跟这个有关。当时启动一个基于Java的大型系统，发现系统报ZipException错误。当时觉得很奇怪，后面好像没什么弄，该异常又没有出现了。我想，当时应该就是文件的句柄数不够用了。
