Running on large project keep getting: java.io.FileNotFoundException - Too many open files #39

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
running on a larger project (some 3.5 million lines of code, about 3500
classes) (JAVA - build 14.0-b16, Ubuntu 9.04 64bit)

quite quickly I will get

 java.io.FileNotFoundException - Too many open files

in the stacktrace below i took out the name of my file and replaced it with
... 

It does look like its opening the same files many many many times..

 "main" java.lang.RuntimeException: java.io.FileNotFoundException: ... (Too
many open files)
