Subject Re: flume 0.9.4 windows version out of memory
Date Mon, 28 Jan 2013 06:49:39 GMT
How about editing registry using regedit?

1. locate memory option parameters in registry:
HKEY_LOCAL_MACHINE > SOFTWARE > Apache Software Foundation > Procrun 2.0 
 > FlumeNode > Parameters > Java

2. Increase values in JvmMs and JvmMx

3. Stop/Start FlumeNode Service via Flume tray icon menu.

-JS
