Error: Java.lang.OutOfMemoryError: Java Heap Space
This error occurs when the java heap set aside for Voyager is maxed out. To resolve this error:
Stop Voyager
Increase the memory (java heap) parameter set for Voyager by editing the Voyager Vmoptions file under Voyager Install > App
If there's enough RAM available on the server where Voyager is running, change the java heap value from 1024 MB to 2048 MB (increase the –Xmx parameter in the Vmoptions file)
Save Vmoptions
Restart Voyager
Note: For a machine with 16 GB of memory, the Xmx parameter can be increased up to –Xmx4096M (maximum of 5000M).
