perhaps some more information would help:
I'm experiencing this on two different boxes with totally different hardware, one located at datacenter and connected via LAN and second one that is sitting on ADSL line.
I have tried all sysctl variables that I could find remotely related to this with no luck, tried compiling kernel with and without DUMMYNET
This are kernel customizations I use:
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
options DUMMYNET
options HZ=1000 # strongly recommended
options IPDIVERT
options IPSTEALTH #support for stealth forwarding
options ACCEPT_FILTER_HTTP # Must be here or AcceptFilter won't work w/Apache2
options DEVICE_POLLING # Imporoves network driver performance
options ZERO_COPY_SOCKETS
device coretemp # On-die temperature sensor on Intel Core and newer CPUs
Is it at least possible to turn of this checks for local IP's - it is most disturbing that I'm getting droped packets at apache jail to mysql jail communication?
