When this error occurs, the VontuManager.log contains an error relating to initializing the VM. This error occurs because a separate JVM is launched to handle the indexing. Even if the EDM is small, the JVM tries to grab a set amount of memory and is unsuccessful.
There are several solutions to the error, "unexpected error creating RAM index...":
- Ensure that your pagefile.sys is larger or preferably twice the size of your physical RAM - Windows memory management is particular in how paging is used. Even if you see Gigs of available memory the actual allocation might not occur as a result of a low pagefile.sys file.
- Reboot the machine, try again to clear all memory buffers
- Allocate more physical memory
- Reduce the max_indexer_memory property in the Vontu/Protect/Config/Indexer.properties file. This property controls how much memory the indexer JVM consumes when launched.
