M204.2126  User's pushdown list overflowed

The user's pushdown list is an internal stack for maintaining state information for user threads across internal Model 204 subroutines. The user pushdown list lives in each user's server. Its size requirement depends on the complexity of the command or SOUL request.

This message is issued whenever Model 204 detects that pushdown list data has spilled into adjacent control structures. Because of potential corruption, the user is restarted.

Response: Increase the size of the user pushdown list with the LPDLST parameter in a UTABLE command. Notify your system manager.

System manager response: If this becomes a frequent occurrence, consider more permanent changes to LPDLST and SERVSIZE, since the pushdown list is a server component.
