I usually run java under libc_r, but if I point java-1.4.2 to libpthreads.so via libmap.conf, within 5 minutes or so I get a kernel panic: Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 00 fault virtual address = 0x54 fault code = supervisor write, page not present instruction pointer = 0x8:0xc0565e78 stack pointer = 0x10:0xdee22b28 frame pointer = 0x10:0xdee22b48 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 753 (java) The system locks hard here (can't break into ddb via serial console), so I don't have a coredump. addr2line says: $ addr2line -f -e kernel.debug 0xc0565e78 setrunqueue ../../../kern/kern_switch.c:402 401 td2 = TAILQ_FIRST(&kg->kg_runq); 402 KASSERT((td2->td_kse == NULL), 403 ("unexpected ke present")); This is with PREEMPTION enabled. -- Dan Nelson dnelson@allantgroup.com
