Change the ownership of all files in <APPIAN_HOME> to the right user.

I changed ownership back to root for all files within <APPIAN_HOME>.. But still only 7 engines started. 9 did not.. Any reason why?

1. Run stop-suite.sh
2. Make sure all k processes shutdown
3. Kill -9 those who remain alive if not using CPU
4. Verify the ownership remains the right way
5. Start again

In a Linux environment you can figure out why they are not starting by looking at the corresponding:
gw-*.log
For example, if EXEC00 is not starting, simply open
gw-process-execution0.log
to see the boot-up process and determine the root cause

Try my suggestion above and see if you have more recent write_to_disk_failure.l files (these were from when the account didn't have privileges to write to the engine database files *.kdb)

Here you are:-

`write_to_disk_failure

Not sure which is the most recent entry but:
1. "Address already in use" means there was still a k process running when you started the engines
2. The "Bad file descriptor" was related to the lack of permissions
It seems this is a new installation, isn't it? If that's the case, simply re-install
