Hi, on a machine 61 days uptime I've just seen this in all the dmesg. The kernel is from FreeBSD 5.2-CURRENT #4: Fri Jul 16 11:53:55 UTC 2004 sources from about 0-3 days before. looks partly similar to kern/68323. I cannot see any changes in raw_ip.c > line 560 within the last two months but a lot of other things have changed since then. --- cut --- malloc(M_WAITOK) of "Mbuf", forcing M_NOWAIT with the following non-sleepable locks held: exclusive sleep mutex rip r = 0 (0xc06871cc) locked @ /u2/src/HEAD/src/sys/netinet/raw_ip.c:740 KDB: stack backtrace: kdb_backtrace(1,c2b1ec00,c2444b40,14,cb48ab50) at kdb_backtrace+0x29 witness_warn(5,0,c05ff4da,c05e4685) at witness_warn+0x182 uma_zalloc_arg(c2444b40,cb48ab74,2) at uma_zalloc_arg+0x38 m_prepend(c2b1ec00,14,2,c2b899e0,c289c370) at m_prepend+0x52 rip_output(c2b1ec00,c2b899e0,23efea9,580,c2b1ec00) at rip_output+0x99 rip_ctlinput(c2b899e0,0,c2b1ec00,c289c370,0) at rip_ctlinput+0x7a2 sosend(c2b899e0,c289c370,cb48ac54,c2b1ec00,0) at sosend+0x5b0 kern_sendit(c29a22c0,3,cb48accc,0,0) at kern_sendit+0xd1 socketpair(c29a22c0,3,cb48accc,0,804f2d4) at socketpair+0x479 sendto(c29a22c0,cb48ad14,6,151,296) at sendto+0x4d syscall(2f,2f,2f,804ed54,804ed54) at syscall+0x1eb Xint0x80_syscall() at Xint0x80_syscall+0x1f --- syscall (133, FreeBSD ELF32, sendto), eip = 0x280e42bf, esp = 0xbfbee80c, ebp = 0xbfbee848 --- --- cut --- PS: I will not be able to test anything related to this before next tue - sorry. if you need further information please let me know and I'll see what I can do. -- Greetings Bjoern A.
