ERROR DESCRIPTION:
NETSTAT OSAINFO may abend when a device has a large number of
registered IP or MAC addresses.
This would be more likely to fail when issued against a
VSwitch controller (eg. DTCVSW1) when the VSwitch has a large
number of guests coupled to it.
For example, in a case with 450 MAC Addresses, this failure
is seen:

PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All users of NETSTAT OSAINFO *
****************************************************************
* PROBLEM DESCRIPTION: *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
If a large number of IP or MAC Addresses are registered on
an OSA device, issuing NETSTAT OSAINFO against that device
may produce an abend. The exact number is variable depending
on the configuration.
PROBLEM CONCLUSION:
The NETSTAT client command sends a request to the TCP/IP
stack to retrieve the OSAINFO data. When the amount of data
returned exceeds 4096 bytes, a logic error in the
initialization of a pointer to the data leads to the
problem. The code in CMNETST has been updated to properly
initialize the pointer.
