I've already solved this issue by rebuilding a 5.3 stable, almost GENERIC kernel (http://webart.lt/~molotov/b10) and by removing any custom sysctl's from loader.conf, the system is running for two days and it seems quite stable. The old kernel is still at /boot/kernel.old/, I will try to debug it as soon as I will get console access to the box. It also seems, that some sysctl tunings, that I haven't mentioned, were critical: kern.ipc.semmni="512" kern.ipc.semmns="1024" kern.ipc.shmall="65535" kern.ipc.shmmax="268435456" kern.ipc.shm_use_phys=1 These were somehow tuned for PostgreSQL, but some of them perhaps were quite crazy values and they are now set to their defaults. If the problem persists with current (or even totally default) system settings, I'll send you the output of the nfsd stack trace. Thanks. -- Simonas Kareiva
