Does anyone know why "werl" runs non-stop on my ArcGIS Data Store server?  It's mostly at 5% of CPU or less, but sometimes it jumps up to 25%.

This is for Tile Cache store only.  It doesn't seem to run on the other Data Store servers.

Yes, if the relational tile store is running, werl.exe should should be running. Similar to how Java applications run in a JVM, Erlang applications run in an Erlang VM process container.

Werl.exe is  Erlang. Erlang is the language the underlying database that powers the Tile Cache store database.

Randall,

Should it be running constantly?  Essentially, did I install it correctly?

Thanks,
