Explanation
 A DISPLAY EE or DISPLAY EEDIAG command that specified
HOSTNAME  filters was entered.  The number of host name resolutions
required to process this display  command would cause VTAM® to exceed the MAXHNRES start option value.

System action
 The DISPLAY EE or DISPLAY EEDIAG command is not
performed.

Operator response
 Wait until some of the previous display commands
requiring host name resolution complete, then issue the display command
again.  The following commands might also be useful:  The D NET,VTAMOPTS,OPTION=MAXHNRES command displays the current
value of  this start option.   If the value is not defined large enough
for your system, contact  your system programmer to increase the value
defined for the MAXHNRES start option.    
The D NET,EEDIAG,TEST=PENDING command queries the display commands
that are  pending host name resolution results. 

 For more information about the MAXHNRES start option,
see z/OS Communications Server: SNA Resource Definition
Reference.

System programmer response
 If the defined or defaulted value
of the MAXHNRES start option is not large  enough for your system
needs, code your preferred  MAXHNRES start option value  in the ATCSTRxx start
list and restart VTAM. See
the MAXHNRES start option in the z/OS Communications Server: SNA Resource Definition
Reference for more information.
