APAR Error Description / Circumvention
-----------------------------------------------
When listing the contents of a directory in service of a client
request, IBM i NetServer exceeded the boundaries of a stack
allocation. Corruption of the stack frame resulted in abnormal
termination of the system with SRCB6000302.
The terminating call stack contained the following modules:
ISF=D7B8BD3193FFCDE0 NIA=FFFFFFFFC90744E4 module
sl_strings+0x1F74
ISF=D7B8BD3193FFCEA0 NIA=FFFFFFFFC9074530 module
sl_strings+0x1FC0
ISF=D7B8BD3193FFCF60 NIA=FFFFFFFFC5703C54 module
zlsNTFinfo+0x9B4
ISF=D7B8BD3193FFD000 NIA=FFFFFFFFC57039F8 module
zlsNTFinfo+0x758
