As previously reported, the NEP is crashing when processing NON-IP XML files. I have checked the system, and both memory and CPU usage appear to be normal. Additionally, there are no major errors in the logs.

It's failed at this point during the PhysicalConfiguration process.
2025-08-23 04:07:03,145 INFO [com.mobinets.nep.npt.business.PhysicalConfigurationManager] (RMI TCP Connection(25)-10.164.168.12) Start PhysicalConfigurationManager.saveConfiguration .savePorts for Interface: [GETH 0/0/7/0/1]

After restart the Jobss, we executed the IP XML import, which extended for more than 8 hours and not finished. During this process, a 'DEADLOCK APPARENT' error was encountered..
We also located a related 'Health Monitor' message that occurred just before the deadlock.
