Third Party Ethernet to Serial driver keeps gets into unresponsive state

[EMENick]

We use Perle's Trueport software (COM Re-director) to create virtual comports on a Windows Server 2012 R2. Starting in May after the Wannacry we received tickets in which the Trueport windows service stops responding and eventually gets closed by windows. We have only seen this issue occur on VMWare servers.

With the patches released in April that addressed security concerns, we'd like to know if any of these patches affected serial communication. We have seen this issue occur on 4 different servers, all in different environments, all running Windows Server 2012 R2 with VMWare with no issues prior.

Additionally, are there any measures that can be taken to reduce the likelihood of services becoming unresponsive due to system resources?

Hello,

Is there any logging that provides information why the redirect shuts down? If you are running this on systems without issue in other environments that have also been patched, it seems to not be the patches, though does not completely rule them out.

Without more information of why it is failing I do not have anything to try.
