A Network Monitor detection server shows as Running Selected, but its event logs show that the packet capture and file reader processes are crashing. What is a possible cause?

• A. The Enforce and Network Monitor servers are running different versions of DLP.
• B. The database is offline.
• C. The server clock is out of sync.
• D. The license has expired.

Answer: (A)

When components aren’t aligned in version, the integration points between them can break in subtle and disruptive ways. Here, the Network Monitor appears to be running, but the packet capture and file reader processes crash because Enforce and Network Monitor are on different DLP versions. The two components rely on the same data formats, APIs, and driver interfaces; a mismatch can cause one component to call interfaces that the other has changed or deprecated, leading to crashes in the processes that perform capture and file reading. If the database were offline, you’d expect broader connectivity problems and error messages about the database rather than crashes of specific subprocesses. A clock that’s out of sync would typically cause timing issues or mismatched timestamps, not crashes of the capture and reader modules. An expired license would generally stop features or the service altogether rather than cause targeted process crashes. Keeping all DLP components on the same version avoids these incompatibilities and stabilizes the monitoring workflows.
