We decided to install a second instance of Nfdump/nfsen for monitoring corp
branch office.
All goes well except i see no data on the port tracker plugin.
In the log i continue to see nftrack crash

I have tried to delete the ports database directory and rebuild.
I double checked permissions on the ports database directory
The three files are seen in the ports database dir
[root@netflow001 bin]# ls -lah /opt/netflow/data/portsDB/ | grep port
-rwxrwxrwx 1 netflow apache 3.1M Jul 26 10:40 ports.stat
-rwxrwxrwx 1 netflow apache 521 Jul 26 12:25 portstat24.txt
-rwxrwxrwx 1 netflow apache 521 Jul 26 10:40 portstat.txt
The only difference between this install and my working on is the fact that
i have the new FlowDoh plugin running.
Details:
CentOS release 6.4 (Final)
nfdump-1.6.10
nfsen-1.3.6p1
Any ideas on how to troubleshoot this?
