After setting up GemFire and starting 2 servers from the same directory according to the "Getting Started" guide I'm trying to run a few quickstart examples. The first example I happen to select was a combination of BenchmarkAckConsumer/Producer. Consumer started OK but when running Producer I got the following IOException:
Exception in thread "main" com.gemstone.gemfire.cache.DiskAccessException: For DiskStore: DEFAULT: Could not lock ".\DRLK_IFDEFAULT.lk". Other JVMs might have created diskstore with same name using the same directory., caused by java.io.IOException: The file ".\DRLK_IFDEFAULT.lk" is being used by another process.
My gemfire.properties file is simple and contains only 2 entries: log-level and locators.
I'm new to this and maybe missing some simple stuff here. Any help will be greatly appreciated.
