Program hangs because of log4j

           Summary: Program hangs because of log4j
           Product: Log4j
           Version: 1.2
          Platform: HP
        OS/Version: HP-UX
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Other
        AssignedTo: log4j-dev@jakarta.apache.org
        ReportedBy: surjit321@yahoo.com


I have a UNIX perl scrip which calls a java program in a loop. The java 
program just prints the arguments received from the perl. The UNIX perl 
program invokes the java program in a loop for 100 times, then goes to sleep 
and redoes the loop.
I have seen that quite often the java program doesn't return which makes the 
perl program to hang. I am using Log4j version 1.2.8 in the java program to do 
loggin. I see the last debug statement in the java program being printed in 
the log file, but due to some reason sometimes the java program doesn't exit.

I modified the java program to have no logging and also to a version where I 
was doing logging and put a System.exit at the end. These two versions never 
got hung, but the original version of the java program gets hung.
Please let me know if this is a known problem in log4j or if you need more 
info from me.
