The system crashes periodically with a kernel panic (panic: sbdrop). The uptimes between two crashes are going from a few hours to a few weeks. The system is a i386, Intel Pentium 4 based with 512MB ram and a 3ware-7000= (twe) raid controller containig 1 raid 5 set with approx. 1.9TB. The kernel is a GENERIC kernel without changes of the config. These are the kernel dumps: Unread portion of the kernel message buffer: panic: sbdrop Uptime: 22h22m7s Dumping 503 MB (2 chunks) chunk 0: 1MB (159 pages) ... ok chunk 1: 503MB (128752 pages) 487 471 455 439 423 407 391 375 359 343 327= 311 295 279 263 247 231 215 199 183 167 151 135 119 103 87 71 55 39 23 7 #0 doadump () at pcpu.h:165 165 __asm __volatile("movl %%fs:0,%0" : "=3Dr" (td)); (kgdb) backtrace #0 doadump () at pcpu.h:165 #1 0xc068d10e in boot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:3= 99 #2 0xc068d680 in panic (fmt=3D0xc090c16a "sbdrop") at /usr/src/sys/kern/kern_shutdown.c:555 #3 0xc06d266c in sbdrop_locked (sb=3D0xc20aca84, len=3D1) at /usr/src/sys/kern/uipc_socket2.c:1157 #4 0xc06d3d93 in sbdrop (sb=3D0xc20aca84, len=3D0) at /usr/src/sys/kern/uipc_socket2.c:1208 #5 0xc0748a7d in tcp_input (m=3D0xc1c09100, off0=3D-1039845124) at /usr/src/sys/netinet/tcp_input.c:1201 #6 0xc0740147 in ip_input (m=3D0xc1c09100) at /usr/src/sys/netinet/ip_input.c:778 #7 0xc07171ff in netisr_processqueue (ni=3D0xc09ca4f8) at /usr/src/sys/net/netisr.c:236 #8 0xc07174be in swi_net (dummy=3D0x0) at /usr/src/sys/net/netisr.c:349 #9 0xc06740e5 in ithread_loop (arg=3D0xc19c3280) at /usr/src/sys/kern/kern_intr.c:547 #10 0xc0673110 in fork_exit (callout=3D0xc067402c , arg=3D0x0= ,=20 frame=3D0x0) at /usr/src/sys/kern/kern_fork.c:789 #11 0xc0894a1c in fork_trampoline () at /usr/src/sys/i386/i386/exception.s:= 208 Now the output of bt full: (kgdb) bt full #0 doadump () at pcpu.h:165 No locals. #1 0xc068d10e in boot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:3= 99 first_buf_printf =3D 1 #2 0xc068d680 in panic (fmt=3D0xc090c16a "sbdrop") at /usr/src/sys/kern/kern_shutdown.c:555 bootopt =3D 260 newpanic =3D 0 buf =3D "sbdrop", '\0' #3 0xc06d266c in sbdrop_locked (sb=3D0xc20aca84, len=3D1) at /usr/src/sys/kern/uipc_socket2.c:1157 m =3D (struct mbuf *) 0x0 next =3D (struct mbuf *) 0x0 #4 0xc06d3d93 in sbdrop (sb=3D0xc20aca84, len=3D0) at /usr/src/sys/kern/uipc_socket2.c:1208 No locals. #5 0xc0748a7d in tcp_input (m=3D0xc1c09100, off0=3D-1039845124) at /usr/src/sys/netinet/tcp_input.c:1201 dbuf =3D "\024\000\000\000\000=BB=C0=C1=A4\033\b=D4=E4=AC\211=C0X= =BA\231=C1=AC\033\b=D4x\034\b=D4=C3M\211=C0G\000\000\000\b\000\000\000(\000= \b=D4(\000l=C0" sbuf =3D "\0003\234=C1l\033\b=D4\200=F2=AD=C1\0003\234=C1\224\033\b= =D4=BF\201\211=C0\0003\234=C1\000\000\000\000\000\000\000\000\000=B9\226=C1= \027\000\000\000\020(=DD=C1" th =3D (struct tcphdr *) 0xc1b2f824 ip =3D (struct ip *) 0xc1b2f810 inp =3D (struct inpcb *) 0xc3ec5ca8 optp =3D (u_char *) 0xc1b2f838 "\001\001\b\n:\r=B7\027\004=CC\236= =F2#E=B2W" optlen =3D 12 len =3D 69 tlen =3D 0 off =3D 32 drop_hdrlen =3D 52 tp =3D (struct tcpcb *) 0xc20538fc thflags =3D 16 so =3D (struct socket *) 0xc20ac9bc todrop =3D 69 acked =3D 69 ourfinisacked =3D 0 needoutput =3D 0 tiwin =3D 5840 to =3D {to_flags =3D 1, to_tsval =3D 973977367, to_tsecr =3D 805188= 98,=20 to_mss =3D 0, to_requested_s_scale =3D 0 '\0', to_nsacks =3D 0 '\0',=20 to_sacks =3D 0x0} headlocked =3D 0 rstreason =3D 69 ip6 =3D (struct ip6_hdr *) 0x0 isipv6 =3D 0 #6 0xc0740147 in ip_input (m=3D0xc1c09100) at /usr/src/sys/netinet/ip_input.c:778 ip =3D (struct ip *) 0xc1b2f810 ia =3D (struct in_ifaddr *) 0xc1c0bb00 ifa =3D (struct ifaddr *) 0xc1c0bb00 checkif =3D 0 hlen =3D 20 sum =3D 0 dchg =3D 0 odst =3D {s_addr =3D 3250633472} #7 0xc07171ff in netisr_processqueue (ni=3D0xc09ca4f8) at /usr/src/sys/net/netisr.c:236 m =3D (struct mbuf *) 0xc1c09100 #8 0xc07174be in swi_net (dummy=3D0x0) at /usr/src/sys/net/netisr.c:349 ni =3D (struct netisr *) 0xc09ca4f8 bits =3D 0 i =3D 0 #9 0xc06740e5 in ithread_loop (arg=3D0xc19c3280) at /usr/src/sys/kern/kern_intr.c:547 ih =3D (struct intrhand *) 0xc19c1080 p =3D (struct proc *) 0xc19b0624 count =3D 0 warned =3D 0 hlen =3D 20 sum =3D 0 dchg =3D 0 odst =3D {s_addr =3D 3250633472} #7 0xc07171ff in netisr_processqueue (ni=3D0xc09ca4f8) at /usr/src/sys/net/netisr.c:236 m =3D (struct mbuf *) 0xc1c09100 #8 0xc07174be in swi_net (dummy=3D0x0) at /usr/src/sys/net/netisr.c:349 ni =3D (struct netisr *) 0xc09ca4f8 bits =3D 0 i =3D 0 #9 0xc06740e5 in ithread_loop (arg=3D0xc19c3280) at /usr/src/sys/kern/kern_intr.c:547 ih =3D (struct intrhand *) 0xc19c1080 p =3D (struct proc *) 0xc19b0624 count =3D 0 warned =3D 0 #10 0xc0673110 in fork_exit (callout=3D0xc067402c , arg=3D0x0= ,=20 frame=3D0x0) at /usr/src/sys/kern/kern_fork.c:789 p =3D (struct proc *) 0xc19b0624 #11 0xc0894a1c in fork_trampoline () at /usr/src/sys/i386/i386/exception.s:= 208 No locals.
