PRTG Probe.exe high CPU

We have a small setup with PRTG and it works great. However, we recently added a probe on to an Azure server to monitor a couple of servers there.

Two of the servers being monitored are set to shut down over night and the schedule I have set up prevents alerts etc, so that's all working. (Servers shut down at 7pm UK time. I don't think this is related but I am mentioning it just in case)

All is OK, except that about 9pm UK time, every night the PRTG Probe.exe goes up to 99% CPU and stays there until I kill it and restart the service.

I've left it over night to see if it makes any difference, but after over 12 hours (and with those servers that go off back up and running again), it's still using up all available CPU.

Any ideas? If I have to I will setup something to restart the probe service daily, but I'd rather fix the cause than the symptom.

PRTG Prove version from the exe is 17.1.28.1032 and is the same version running on our other probes without issue.

Thanks in advance.

Dear acoles

This issue has been fixed in the latest release. Please download the update. Run this file on the PRTG core server (not on the remote probe.) The existing configuration will be kept. Once the core server is updated, it transmits the remote probe installer to each remote probe.

Do we need to do anything on the remote probes or will they shutdown and update on their own?

Remote probes usually update themselves once the core is updated. If a restart is required, PRTG notifies you.

In case the probe update fails, please go to the web interface, Setup / Download / Remote Probe Installer to obtain the remote probe update manually.
