Symptom	Problem Determination
`AWSSTA140E – Initialization failure after license obtained`	Ensure that you are starting ZD&T from the home directory of the user who is created for running ZD&T. Ensure that you have run the `aws_bashrc` command while logged on as that user, and from that user's home directory.
The following messages occur during startup: `AWSECH004S Unable to define RAS/FEDC memory, RC=-3. AWSECH004S Unable to define RAS/FEDC memory, RC=-3.`	This message is seen with many `awsckd` definitions. The Linux® kernel setting `SHMMNI`, which sets the system-wide maximum number of shared memory segments, is probably too low. The default is `4096`. Try increasing this setting by adding `kernel.shmmni = 8192` to `/etc/sysctl.conf` and activate it using the command `sysctl -p`.
The following message occurs when ipling z/VM® 6.2 “CP requires hardware features not available on this processor”	Older z/VM V6R2 maintenance levels may not work with zPDT® Version 1 Release 6. Either migrate to z/VM V6R3 or ensure PTF VM65007 is applied to your z/VM V6R2 system.
