In the past we were able to reconnect to a TSO session when our VPN 
disconnected via the use of Gilbert St Flour's IKJEFLN2.  The implementation of 
LOGONHERE made this exit unnecessary.  However, now we can no longer reconnect 
to a session when the VPN disconnects, due to a network issue or it just goes 
down, even though we have an S for RECONNECT in the USS display.   Now we 
immediately get the following messages:

IKT100I USERID userid       CANCELED DUE TO UNCONDITIONAL LOGOFF
IKT122I IPADDR..PORT nnn.nnn.nnn.nnn..50569
IEF450I userid proc procstep - ABEND=S622 U0000 REASON=00000000

Both LOGONHERE and RECONLIM are defaulted (YES and 20 respectively).  I am able 
to switch a TSO session to another TN3270 session without a problem but not 
when the VPN connection goes down (after it comes back up well within the 20 
minutes, of course).  All I can think is that some TCPIP parameter like 
DISCONNECTABLE or INACTIVE was not carried forward when we upgraded our z/OS 
even though the defaults for these parameters seem fine.   

I logon using the DNS name of one of our z/OS systems.  I know I could logon to 
the system using a VM DIAL command but when I do that, I lose the the use of 
the ATTN on the keyboard to interrupt a long running REXX or program.  

Any help would be appreciated but I need a fix not a workaround.
