Dynatrace server service stopped automatically


Hi All,

I migrated dynatrace 7.0 to a new VM but i noticed that the dynatrace service stops automatically. Looking in the logs i have thise error :

I tried to change version of java and increase the memory size but it ddoes not solve the problem.

Someone would have an idea for solving this problem?

Thank you.

Hi Fouad, you don't mention how much memory your server had / has so it's impossible to help further.

Please ensure your server meets the system requirements for the size of your deployment:

Feel free to provide additional info (how many agents / what server sizing have you selected / exactly what resources does your server have) and I'll try and help...


Hi Adam,

Thank you for the answer.

I have 60 agents, when i try to connect DT client, the service of dynatrace server stops automatically.

Bellow configuration of my VM :

Your memory settings are set to utilize an Extra Large server or 32 GB of RAM in your system, your VM only has 16 available to it. I would either increase the VM to have it properly sized or change the memory portion to small to get the server to at least start.

"The paging file is too small for this operation to complete" indicates that you need to increase the memory reserved for the Paging File. For a how-to see this page:


Hi all,

Thank you for your answers. I increased the memory 16GB ==>32GB and everything works normally.
