The error message "Request daemon can't accept sessions" occurs when another instance of bpjava-msvc tries to run when bpjava-msvc is already registered with inetd. This can be caused when a manual attempt is made to start bpjava-msvc or if the /etc/inetd.conf has a typo in the entry for bpjava-msvc.

The Java GUI will fail with the following error:

 Unable to login, status: 505
 Can not connect to the NB-Java authentication service on
 master on the configured port - 13722

 Exception: java.lang.NumberFormatException: another
 Exception message: another

If this error occurs, then try to telnet to port 13722 on the system. If it fails with the following error, then there is most likely a typo in the /etc/inetd.conf file.  

 # telnet master 13722
 Trying...
 Connected to master.
 Escape character is '^]'.
   request daemon can't accept sessions
   another instance may already be running.
   Address already in use
 Connection closed by foreign host.

Then check the /etc/inetd.conf file for errors. A typo with the -transient option can trigger this error.

An incorrect entry that would trigger this error would be:
bpjava-msvc     stream  tcp     nowait  root    /usr/openv/netbackup/bin/bpjava-msvc bpjava-msvc -transient

To correct this problem do the following:

1. Edit the /etc/inetd.conf file and make sure the bpjava-msvc line is setup as follows:
bpjava-msvc     stream  tcp     nowait  root    /usr/openv/netbackup/bin/bpjava-msvc bpjava-msvc -transient

Note: This should all be on one line. The -transient should be one word with no spaces.

2. Save the file

3. Then send a SIGHUP to inetd
# ps -ef |grep inetd

  This will show the <PID> for inetd. Use this in the next command:
# kill -HUP <PID>

  This will cause inetd to re-read its configuration file.

4. Then try to log in via the GUI
