Aack child crashed on Solaris

[Fred Backman]

I've got another problem on my Solaris machine (5.7), and this time I get a "Aack child crashed" when I try to send to local users. Below is the trace output (truss) of qmail-lspawn. Please can anyone advice what this might be? There is no .qmail file so that can't be it.   officesun2{root}# truss -p 28661 poll(0xFFBEFCA8, 1, -1)         (sleeping...) poll(0xFFBEFCA8, 1, -1)                         = 1 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 read(0, "\0 9 / 4 5 4 3 4\0 r o o".., 1024)     = 71 open("9/45434", O_RDONLY|O_NDELAY)              = 2 fstat(2, 0xFFBEFBA8)                            = 0 pipe()                                          = 3 [4] fcntl(3, F_SETFD, 0x00000001)                   = 0 fork()                                          = 45 close(2)                                        = 0 fcntl(4, F_SETFD, 0x00000001)                   = 0 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0     Received signal #18, SIGCLD, in poll() [caught]       siginfo: SIGCLD CLD_EXITED pid=45 status=0x006F poll(0xFFBEFC90, 2, -1)                         Err#4 EINTR waitid(P_ALL, 0, 0xFFBEF748, WEXITED|WTRAPPED|WNOHANG) = 0 close(4)                                        = 0 waitid(P_ALL, 0, 0xFFBEF748, WEXITED|WTRAPPED|WNOHANG) Err#10 ECHILD setcontext(0xFFBEF978) sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 poll(0xFFBEFC90, 2, -1)                         = 1 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 read(3, " A a c k ,   c h i l d  ".., 128)      = 30 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 poll(0xFFBEFC90, 2, -1)                         = 1 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 read(3, 0x00029398, 128)                        = 0 write(1, "\0 Z A a c k ,   c h i l".., 33)      = 33 close(3)                                        = 0 sigprocmask(SIG_SETMASK, 0xFFBEFCB8, 0x00000000) = 0 poll(0xFFBEFCA8, 1, -1)         (sleeping...)
