4299.0. "Multiple sessions. Error 59. Pathworks hangs" by AUBER::CORNU (Valerie CORNU - CSC Evry FRANCE) Wed May 21 1997 05:51

	Hi,

	One customer encounters a hang problem of Pathworks since V5.0D.
	Still in 5.0E, the problem remains.
	Symptoms:

		PC's are hung
		$net session gives multiple sessions for the same PC
			(about 4 to 10). The username is the right 
		        username and not GUEST. It doesn't display
			the end of the list because it displays "error 59"
			an unexpected error occured.
		VMS users can work.
		Stop and restart Pathworks : not the solution.
		Reboot is required.

	PC's are Win95 PC's with NETBEUI and TCPIP.
	There's an alias name but the PC's don't use it.
	There's no NT4 client.
	The PC's seen multiple times are really connected PC's.
	The server is configured for 180 PC's and the problem occurs with
	40 PC's connected.
	No information registered with the $admin/analyze command.

	Why so many sessions ?
	
	Thanks,

	Valerie

    Valerie,
    
    Is the server a VAX or Alpha and what's the OpenVMS version?
    
    What IP stack (and version) is installed on the server?
    
    Does EVERY client have multiple sessions?  
    
    Have you used:
    
    $ @SYS$STARTUP:PWRK$DEFINE_COMMANDS
    $ @NBSHOW KNBSTATUS 	! TCP/IP
    $ @NBSHOW NBSTATUS  	! NetBEUI
    
    to determine the problem is occurring over both NetBEUI and IP?  BTW,
    the NBSHOW output will display either the server's nodename or PW
    cluster alias name under the Local Name column (session status
    section) - so you can confirm whether or not the PW cluster alias name
    is being used (for NetBEUI and IP anyway, not so for DECnet sessions).
    
    Does $ MC NCP SH K LINE COUNT show send/receive failures, high
    collision ratio, user/system buffer unavailable?
    
    Any errors in PWRK$LMLOGS:PWRK$LMMCP_nodename.LOG?
     "    "    "  PWRK$LOGS:PWRK$NBDAEMON_nodename.LOG?
     "    "    "  PWRK$LOGS:PWRK$KNBDAEMON_nodename.LOG?
     "    "    "  SYS$MANAGER:UCX$PWIPACP_nodename.LOG? (if using UCX)
    
    Does $ PWVER ALL show any old versions for PATHWORKS images (especially
    the PWRK$STREAMS* images)?

    Probably should also provide a general (at least) overview of the
    network configuration...

Valerie,

Even more questions:

>		PC's are hung

Are the PC's not able to fucntion at all?  Do they need a hard reboot,
or do you mean they sit forever waiting for a command to complete?

Is that the VMS server you are stopping and restarting?  If so, does the
restart show multiple sessions shortly after it comes up?  Is the reboot
required a server or client reboot?

	Answers:

	Pathworks installed on an ALPHA with OpenVMS V6.2

	IP Stack is UCX V3.3 ECO 12

	All client don't have multiple sessions. Juste some.

	NBSHOW NBSTATUS : Pc's are connected to the node name (not the
			  Alias name). But the alias name appears 

	NBSHOW KNBSTATUS : Pc's are connected tot the node name (not
			  the alis name).

	The dcl command mc ncp sh k line count reveals no problem for
	send/receive failures, collisions and user/system buffers unavai-
	lable.
	
	The customer has a version limit of 3 for the log files so we
	didn't have the .logs which correspond to the date when the problem	
	occured. Whe changed this to keep them for the next time.

	$PWVER  gives Pathworks V5.0-500E for all the images (PWRK$STREAMS
	images are PWRK$STREAMSOS_V6 and PWRK$STREAMSOS_V7).

	When the problem occurs, all the PC's are hung.
	On the server, if you restart Pathworks, you always see the sessions
	on the server. The unique solution is to reboot the alpha.

	Network configuration: 

		Server ---- Decswitch --- Dechub -----PC (Twisted Pair)
		
	It's a new installation because they're in a new building.

	Thanks,

	Valerie

    Don't really understand if your seeing a problem.
    
    It could be that 1 client has 2 sessions, 1 to the alias and 1 to the
    nodename. Also there could be multi-sessions for a very short time if
    a client detected a disconnect (due to NW errors) and the server didn't
    notice it. Then client reconnects and the other session will timeout
    eventually when the keep alive timer expires.
    
    The other problem that none of the clients do anything looks more like
    a real problem. Perform some actions to see if server still runs. Most
    of these problems are network related, but it could be that the server
    hangs.
    - Check process states.
    - Check if server responds locally.
    - Check the net - IRIS.
