Hello,

I have setup NetFlow colector v6 to receive flows from 3 devices, but today, 4 days after i have started the collector, i receive the folowing error and i'm unable to generate reports anymore:

[2009-01-08 11:13:59 EET] ERROR com.cisco.nfc.report.ReportBuilder - An unexpected error occurred.

java.lang.OutOfMemoryError: Java heap space

I searched on net and it seems that i have to set higher heap space memory for java. Does anybody know how to rezolv this issue on Red Hat?

It seem like that the JVM has run out of all the memory that has been allocated to it. You can change the amount of memory allocated for use by your JVM using the -Xms and -Xmx command line parameters.
