Posted on by 244

Hi, 

We had developed a DLL using .Net Visual studio Professional Edition and .Net framework. The purpose of DLL is to communication with serial comm port. After a certain amount of time or transactions when we send to request to serial comm port the request will not sent target device via comm port and after restarting the application it works correctly. We don't see any issues in Event viewer.

Any inputs why it is happening ?

Appreciate your help.

    Hi, I'm not quite sure, is it exceeding NAV's Operational Limits?

    https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/operational-limits-online

    In addition, NAV 2009 has been out of service for a long time, please upgrade to the latest version as soon as possible.

    Hello,

    We currently do not have dedicated Dev support via the Dynamics 365 Business Central forums, but I wanted to provide you some additional resources to assist. If you need assistance with debugging or coding I would recommend discussing this on one of our communities.

    www.yammer.com/dynamicsnavdev

    I will open this up to the community in case they have something to add.

    Thanks.
