we are running into a very strange issue when exporting the Portal for ArcGIS Site. The Portal crashes and the Portal log has the following error message:
Failed to export site. Das Portal-Repository konnte nicht exportiert werden. java.lang.OutOfMemoryError: GC overhead limit exceeded
("The Portal Repository cannot be exported")
The corresponding error message can also be found in the tomcat log of the Portal instance:
SEVERE [https-jsse-nio2-7443-exec-42] com.sun.jersey.spi.container.ContainerResponse.mapMappableContainerException The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container
java.lang.OutOfMemoryError: GC overhead limit exceeded
The Portal does contain a lot of elements and more than 100GB in the content directory that needs to be exported. Maybe the export is creating too many temporary files and the garbage collector needs all available resources?
Does anyone has an idea how to solve this issue?
