FME Startup Python Script: Kerberos Ticket Cache not updated

We have a startup python script that will run a kinit process using a keytab file on the server. Unfortunately it appears that even though the kinit was successful and the Kerberos ticket was created correctly, FME is not able to see the newly created ticket in the Kerberos ticket cache. Once the current FME process terminates any new FME processes after wards can see the new ticket. It seems to me the Kerberos ticket cache is read into memory with the initial FME.exe starts and updates are not known about by the FME process. Any idea how make the ticket cache update during the current FME process?

Any ideas or work arounds would be helpful! Current work around idea is to have a separate FME process run separately to generate the Kerberos tickets.

Thanks in advance!!
