On AIX® systems, an AIX APAR causes the Launcher to crash or hang when spawning processes on 64-bit WebSphere Transformation Extender.
Memory corruption causes random Launcher process crashes or hangs.
A known AIX problem can cause memory corruption in processes that use malloc buckets.
Resolving the problem
Edit the $DTX_HOME_DIR/bin/launcher.sh file and comment the lines as shown below:
# if [ "`uname`" = "AIX" ]
# export MALLOCOPTIONS=pool,buckets,bucket_sizing_factor:16,multiheap:8,considersize
