Hi,
I had "kmem_map too small" panic on 5.0-CURRENT/i386 as of Dec. 19 2002.
It often occurred when the machine was running under heavy system
loads (e.g. make -j20 release).
|panic: kmem_malloc(4096): kmem_map too small: 275378176 total allocated
|cpuid = 2; lapic.id = 01000000
|boot() called on cpu#2
|
|syncing disks, buffers remaining... panic: bwrite: buffer is not busy???
|cpuid = 2; lapic.id = 01000000
|boot() called on cpu#2
|Uptime: 13h56m30s
|Dumping 3071 MB
|ata0: resetting devices ..
The machine's kernel is configured with the additional options: SMP and
APIC_IO (4 CPUs are detected). The results of backtrace are:
