General Support / NetXMS Server 6.0.0 Memory Leak
February 09, 2026, 11:30:43 PM
Hello Everyone:

I am currently running a NetXMS Server Version 6.0.0. I recently upgraded it from 5.2.8 and I have experienced the same issue from the prior version to the current version. It appears that the server begins with low RAM utilization, but increases at a consistent rate until it maxes out the available memory, then it idles with about 500mb of free RAM available.



Above is the chart depicting RAM utilization. The server has 16gb of RAM allocated to it. I have tried different amounts of RAM. Previously it had 32gb of RAM allocated to it. The random peaks have to do with server maintenance and shouldn't be related to NXMS, but notice that there are dips, and consistent increases in memory utilization until I jump in to do something.

Each dip in memory utilization in the chart is a server reboot. The rate of increase seems to be about 1.8gb per day.

Are there any known memory leak issues with NetXMS? I assumed the issue would have been fixed with NetXMS v6.0.0.
