@BigPalo sounds strange 😛
Prior to waisting time with troubleshooting I would recommend that you upgrade to the recommended version of PAN-OS 9.0 which is 9.0.13. The list of fixes which were implemented between 9.0.9 and 9.0.13 is almost endless, so the chances are good that this restart no longer happens after the update and if it still does, then troubleshooting this problem will make sense.
Yup and upgrade sounds the best. You can also check the masterd, ms.log and Devsrvr log files for info. For more information about the palo alto logs:
All right, then lets begin with troubleshooting.
Easiest way is to check the last changes since the last working commit. Is there maybe a change that looks "special"? For example a space character in the port attribute of a service object.
Next you continue with checking the devsrv.log file directly after a failed commit.
