I had repeated the panic by reset debug.mpsafenet from 0 to 1, after that, the system automatically reboot after several hours, and if debug.mpsafenet was set to 0, the system is stable. so i guess this is a tcp stack or NIC driver SMP thread-safe issue, normally my server got over 1000 interrupts/s on bge, I have plan to replace the onboard bge NIC to fxp and set debug.mpsafenet to 1 to see what will happen this week. -- Young Lee On Thu, 31 Mar 2005 18:03:08 +0200 Uzi Klein <uzi@bmby.com> wrote: > Young Lee wrote: > > Thank you very much.
