 ERROR DESCRIPTION:
 TCPIP machine loops when RouteD is started. Looking at the
 traces it was determined that TCPIP is looping in TCTREEP
 in procedure FillIpRoutingKey. This code was rewritten in APAR
 PQ46571 (and sysroute APAR PQ50059).
 Problem is in base code for VM TCP/IP R420.

 ****************************************************************
 * USERS AFFECTED: All TCP/IP users.                            *

 * PROBLEM DESCRIPTION: TCPIP machine loops when processing the *
 *                      GATEWAY statement or when starting up   *
 *                      RouteD or MPRoute.                      *

 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 TCP/IP is looping in the FillIpRoutingKey procedure (TCTREEP)
 while trying to determine the routing key.
 
 PROBLEM CONCLUSION:
 The subnetmask and the class mask are used to determine the
 routing key.  They are declared to be unsignedintegertype, but
 the assembler instructions generated are treating them as signed
 fields. This causes TCPIP to loop.
 The code was changed to call an assembler routine COMPLOGC for
 all the subnetmasks comparisons.
