# # OPTIONAL: Maximum Java Heap Size (in MB) wrapper.java.maxmemory=2048 changes back to default whenever MIDServer restarts.

[bhanupratap2203]

For network components discovery we need to increase the JVM from default 1024 to 2048 or 4096 MB in \agent\conf\wrapper-override.conf file . We change it and then save it. Restarts the mid server and then it shows the new JVM which we set (we are following the instructions as https://docs.servicenow.com/bundle/orlando-servicenow-platform/page/product/mid-server/task/t_MIDSer...).

After few days the JVM size changes to default by its own.

What could be the reason of this? How can we prevent this modification by its own.
