Hello, with current sources from today i get a whole lot of these on an nfs server when building world over nfs. malloc(M_WAITOK) of "Mbuf", forcing M_NOWAIT with the following non-sleepable locks held: exclusive sleep mutex inp (tcpinp) r = 0 (0xc13e5b1c) locked @ /storage/src/sys/netinet/tcp_usrreq.c:616 Stack backtrace: backtrace(c0744604,cbb53a4c,1,179,c13f5700) at backtrace+0x17 witness_warn(5,0,c06d383e,c06bdebe,c06be99e) at witness_warn+0x1b5 uma_zalloc_arg(c0c21b00,cbb53a80,2,fa,0) at uma_zalloc_arg+0x4c nfs_realign(c1650424,28,c06ccf37,29d,cbb53ac0) at nfs_realign+0xb4 nfsrv_getstream(c1650400,1,c06ccf37,1d5,0) at nfsrv_getstream+0x36d nfsrv_rcv(c144813c,c1650400,1,19a,c13e745c) at nfsrv_rcv+0x19d sowakeup(c144813c,c144818c,c06cacef,4e2,108) at sowakeup+0x101 tcp_input(c13f5700,14,c11a8000,1,0) at tcp_input+0x1120 ip_input(c13f5700,0,c06c8872,95,c0745638) at ip_input+0x945 netisr_processqueue(c0745638,0,c06c8872,fd,c1107240) at netisr_processqueue+0x8e swi_net(0,0,c06bcf17,270,0) at swi_net+0xa3 ithread_loop(c10dad80,cbb53d48,c06bccfa,328,0) at ithread_loop+0x182 fork_exit(c0502590,c10dad80,cbb53d48) at fork_exit+0xc2 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xcbb53d7c, ebp = 0 --- Regards, flo
