Access violation at address

What does the error message "Access violation at address [...] in module 'PRTG Probe.exe'. Read of address [...]" represent for the sensors. I am receiving this error message for an incredible amount of sensors on many different devices at random times, usually late at night. By looking at the logs, it appears this error message begins appearing and approximately 30 minutes later, an incredible number of ping sensors all start to report and alert out that they're in the down state. This includes servers and networking equipment. Based on the small time frame and chain of events in the logs, there definitely appears to be a correlation.

I've also had trouble determining what exactly that error message represents. What does the "Access violation at address" error represent?

Hello there,

"PRTG Probe.exe" is the service that runs the sensor queries and for some reason it appears to crash. Since there is no single simple answer to why this happens, please send us a support bundle with logs, so we can investigate the issue.

Kind regards,

Erhard
