The NLM (rpc.lockd) wouldn't start up because it had a problem contacting the NSM (rpc.statd) for a while, but I don't see that with a Feb.29 kernel. (I don't know exactly which commits broke/fixed it, but they are post-9.0, I'm pretty sure.) While here, I will mention that if you don't need multiple clients to see each others byte range locks (ie. they are sharing/locking the same files concurrently), then using the "nolockd" option to avoid the NLM is a good idea. rick > > After a few hours the nfs client is crashing like this: > > > Mar 4 13:55:33 hosting01 kernel: Fatal trap 12: page fault while in > kernel mode > Mar 4 13:55:33 hosting01 kernel: cpuid = 1; > Mar 4 13:55:33 hosting01 kernel: NLM: failed to contact remote > rpcbind, > stat = 0, port = 0 > Mar 4 13:55:33 hosting01 kernel: apic id = 07 > Mar 4 13:55:33 hosting01 kernel: fault virtual address = 0x18 > Mar 4 13:55:33 hosting01 kernel: fault code = supervisor > write data, page not present > Mar 4 13:55:33 hosting01 kernel: instruction pointer = > 0x20:0xffffffff807c4b0b > Mar 4 13:55:33 hosting01 kernel: > Mar 4 13:55:33 hosting01 kernel: stack pointer = > 0x28:0xffffff84916c1ec0 > Mar 4 13:55:33 hosting01 kernel: NLM: failed to contact remote > rpcbind, > stat = 0, port = 0 > Mar 4 13:55:33 hosting01 kernel: > Mar 4 13:55:33 hosting01 kernel: frame pointer = > 0x28:0xffffff84916c2070 > Mar 4 13:55:33 hosting01 kernel: code segment = base 0x0, > limit 0xfffff, type 0x1b > Mar 4 13:55:33 hosting01 kernel: = DPL 0, pres 1, long 1, def32 0, > gran 1 > Mar 4 13:55:33 hosting01 kernel: > Mar 4 13:55:33 hosting01 kernel: processor eflags = interrupt > enabled, > > > Any ideas how i can fix this?
