FYI. We're not running Solaris, but Linux SL 3.0.5. We are running
version 4.1.10 of IP Filter. I posted a while back that we have problems with
the entire system freezing. It completely locks up and no one can do anything
locally or remotely. I have to press the reset button, power cycle the
system, and then restore some system files from backup copies from rescue
mode. 99.9% of the time it only happens when I update the filter list. Only
once has it ever done it out of the blue for no apparent reason. None of the
logs show any problems.
I've manage to reduce the problems by changing the default startup script
so that it doesn't shut ipfilter completely down and then start it from
scratch any more. It now loads the new filter list in the inactive buffer and
then swaps the active and inactive buffers. Also disconnecting the VERY busy
outside network connection for at least 30 seconds before the update seems to
help. Not a very good solution, but that's what we have to do.
