           Summary: java fails to bind on port 80
           Product: Commons
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: Daemon
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: obender@gmail.com


Platform is Ubuntu Linux, kernel 2.6.15 amd64 smp on a dual core processor.
When I start Tomcat with jsvc and the Http connector on port 80 java fails to
bind on port 80. I added an extra debug statement in set_caps to tell me when
set_caps is called. In catalina.out I see before java even tries to bind, three
calls: the first with the value 1216, second with 1024 (CAP_NET_BIND_SERVICE)
and the last with 0 (downgrade).
After commenting out set_caps(0) from the jsvc-unix.c Tomcat starts ok.

What is the reason for the downgrade happening so soon? Is it a race condition
turned bad by the use of a multiprocessor?

BTW, the Readme should mention that the module capabilities should be loaded.

apache tomcat 5.5.15

$ java -version
java version "1.6.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-beta-b59g)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-beta-b59g, mixed mode)

I might have tried 1.5.0_06 as well, I can no longer remember.

What is the error message in logs/catalina.out?
Aren't you using -user root?
