UrBackup Client at idle time it uses one core per 100%


I have a windows client version 2.4.8 at idle time it uses one core per 100%

Could you create a memory dump of the process while this occurrs? (howto: https://support.microsoft.com/en-us/help/931673/how-to-create-a-user-mode-process-dump-file-in-windows )

it always consumes 100% of a single core


link to memory dump.

Thanks! Could you send the client log file as well?

Sorry, no hints yet w.r.t. the cause :confused:

Could you capture a bit of what UrBackupClientBackend.exe does with https://docs.microsoft.com/de-de/sysinternals/downloads/procmon and send that as well?

I am experiencing the exact same issue. Windows Client version 2.4.8, Windows 7 64-bit PC.

No hints either. Could be it is caused by ipv6. If you add


to C:\Program files\UrBackup\args.txt and it doesn’t occur that would confirm this.

Well I’ll try. If I restart the service it stops using the CPU at 100% for a while.

After IPv6 is disabled, everything is fine.
