First guess based on those symptoms (but really guessing, not enough info to tell you much) - you're running out states, and it's syncing those to the secondary so both are running out of states. _______________________________________________ List mailing list [email protected] http://lists.pfsense.org/mailman/listinfo/list Chris Thanks for your reply. When the lockup occured we had less then 2MB of traffice on the system. I am unsure if the states would be full but I think it unlikely. I will watch them to see. Current: State table size Show states MBUF Usage 11526/25600 Based on this should I up my State Table Size? My memory never goes above 10% usage either. Thanks Bryant Ok I have some more info after looking at the RRD graphs. I noticed a major increase in memory usage leading up to the two lockups on one of the carp clusters. Normal memory is at 15% usage. The memory usage increased up to 40% before the lockups. Because I am using the nanobsd build I loose the last 12 hours of RRD so it does not contain the acutall lockup usages. but I can see the increase over approx the 24 hour period before. So there is somthing going on there. Are there logs stored some where that might show what is taking the memory over the time covered in the increased memory usage times? If I change one of the routers over to a Hard Drive install would I get more up to date logs in the event of a reset? Thanks Bryant
