Bad File Descriptor

Asked by WA

Hi,

I am using the benchmark SPECjvm2008 that depends on the java application and i am also using the intel pin tool to extract memory traces from this benchmark,after that i am storing these memory traces in a file of type gzFile.

My Problem is that gzwrite returns the following error :
ERROR: Bad file descriptor

So please would anyone suggest me a solution or give me any hints?

Thank You in advance for time and effort.

Best Regards

How did you install the Java you are using?
Do Java test pages (like http://www.java.com/en/download/installed.jsp) work ok?

Thanks

I installed Sun Java 6 at http://www.webupd8.org/2012/11/oracle-sun-java-6-installer-available.html.

I think that the "ERROR: Bad file descriptor" is due to the gzfile is closed and then there it is a try for writing in it after closing.
I don't understand how this occurs as I am closing the gzfile ONLY in an exit function.

I guess that this may be due to JRE threads,so is there any option i can use to set only one running thread for the JRE ?

Thanks
