Dear SCO Customer,

The enclosed Support Level Supplement (SLS) PTF3005B, the Netmgt Shared 
Memory Supplement corrects the nws core dump and netmgt shared memory 
corruption that occurs when netmgt is enabled using "nwcm -s nwum=on".
 

Symptom:
--------

libnwu.so distributed in SLS PTF3005B causes nws to core dump on start.

If netmgt is enabled using "nwcm -s nwum=on", the netmgt shared memory 
segment will be corrupted. Further manipulation of data in shared memory 
by netmgt may result in unpredictable results, such as core dumps.

PTF3005B should only be installed on SCO UnixWare Application Server
