java.lang.OutOfMemoryError: unable to create new native thread

           Summary: java.lang.OutOfMemoryError: unable to create new native
                    thread
           Product: POI
           Version: 2.0-pre2
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: HSSF
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Hello,

My system is weblogic 6.1 and solaris 5.8. The JDK is 1.3.1

I use HSSF to generate an excel file that sizes 550kb (so a big file)

It works 2 times, the third there is an error �java.lang.OutOfMemoryError: 
unable to create new native thread�

I've tried with the option -verbosegc to see the works of the garbage collector:

There is a need of lot of memory for HSSF work, but when the exception is 
raised, there is plenty of memory available. (In fact, I see that the used 
memory goes from 9M to 25M for the generation of one file, go back to 9M after 
the file generation)


So I suppose there is a memory leak (but in a �native call�?) and it may be 
linked to the OS/JDK
