including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the 'IBM License Agreement for Machine

APAR Error Description / Circumvention

-------------------------------------------------
IBM i NetServer is active but all users are unable to map
NetServer drives. Mapping using a Windows graphical user
interface fails with generic 'cannot access \\<ip>...' message.
NET USE fails with 'system error 121. The semaphore timeout
period has expired.'  LIC log major code 1000 and minor code
2203 for task SMBCONNWORKER may be logged at the time of the
connection failure.

CORRECTION FOR APAR 'MA48382' :
-------------------------------
Multiple heap memory leaks have been identified in IBM i
NetServer.  This PTF corrects the server memory management to
prevent future memory leaks.  Any previously leaked temporary
storage will be recovered on the next system IPL.

An IPL of the system will be required to restore NetServer
function if the NetServer heap grows to maximum size prior to
application of this PTF.

CIRCUMVENTION FOR APAR 'MA48382' :
----------------------------------
None.
