Dear all, I have found pfsense a very nice opensource firewall since half-an-year ago. After intensive digging at google and testing, i had decided to migrate the firewall to pfsense. And it always looks good, failover are always smooth and without service interruption.
However problem arise since a month ago, i had found the firewall will automatically failover to the standby pfsense... This won cause any interruption to the service, so i may notice at after daily check... It always failover in the busiest time when the bandwidth usage suddenly surge for 2xMB in a minute. I have used to switch on ntop for monitoring the server usage and it eat up almost half of the CPU usage, so i decide to turn it off but it is no luck..... Here are the detail of my firewall configuration. Hardware : PE 1950 with 4GB of RAM Pfsense version : 1.2 RELEASE Bandwidth usage: 20Mbit/s at non business hour, will surge to 60 Mbit/s during business hour CPU Usage : Under 10 % with ntop switch off CARP VIP : over 150 I had search through the forum and mailing list and i think it it relativly "small" scale. And i suspect the problem are cause by the CARP??, coz i only got about 100 VIP only half-an-year ago. How is the mechanise of pfsense for monitoring the link status? Thanks all for reading and hope i may be able to find some help to find the cause of this problem. Regards, Frankie
