507.0. "x29 processes hang" by TIMAMD::JCUENCA () Tue Apr 01 1997 03:32

    Hi,

We have a customer problem where the x.29 connection goes very slowly or hang,
this is alpha machine acting as X25 access while the x25 node connector is a
DECNIS. 

Several processes at the alpha system are hang. Most the of them are DSN copies
or DSN host connections (DSN is part of the AES software) but we have also seen 
the same problem with set host /x29 application.

    What may be seen from the above data is that the ports on the DECNIS
    are in "Cleared" state while the port associated at the alpha system
    is on "Running" state.
    
    Any hints to follow with the troubleshooting of the problem?
    
    This note is crossposted in the DECNIS conference.
    
    Thanks in advance,
