And presumably no backtrace/dump possible? If you're not using a serial console, you might want to try it and see if you get more reliable access to the debugger. The panic message means that the kernel ran out of address space for kernel memory allocation, which is typically a sign of one of two things: (1) a kernel memory leak, or (2) lack of an allocation/resource bound for some type of allocation, or alternatively, a scaling factor for the resource bound that permits too much allocation (perhaps scaled to physical memory). It would be interesting, if this is pretty reproduceable, to see the output of a series of calls to vmstat -m and vmstat -z leading up to the panic, to see if we can track down what is getting allocated "too much". To work around the problem, you can increase the amount of address space allocated to kernel memory, or you might try reducing the amount of memory in the machine and see if that fixes the scaling factor. Getting a dump of the kernel in its toasted state would be highly desirable, as it's possible to run vmstat on the kernel dump to see what state memory allocation is in. Using a serial console might let you get further into the debugger... > > Regards > estartu > > ---- Bootmsg ---- > > Copyright (c) 1992-2003 The FreeBSD Project. > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > The Regents of the University of California.
