Recently I've clean-installed Mandrake 9.2 beta2 (formatting the '/' partition, and leaving only '/home' intact), and the problem still exists. The symptoms are: after some time the system is running, it gets impossible t start new shell processes - bash,csh, any. All applications that try to launch a shell for some task hang at that stage too - so non-interactive shells cannot start too. The shells that are already started are working fine - it's only impossible to start new ones. I've run a screen session with multiple windows and waited for the problem to occur, and then did strace on various programs that launch shells. They look similarly - they susually hang in waitpit() or read() function. For example this strace end comes from bash: <snip> stat64("/bin/bash", {st_mode=S_IFREG|0755, st_size=641868, ...}) = 0 getpgrp() = 5960 rt_sigaction(SIGCHLD, {0x80776a0, [], SA_RESTORER, 0x40051c68}, {SIG_DFL}, 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [RTMIN], 8) = 0 fcntl64(0, F_GETFL) = 0x2 (flags O_RDWR) fstat64(0, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 5), ...}) = 0 _llseek(0, 0, 0xbfffefe8, SEEK_CUR) = -1 ESPIPE (Illegal seek) rt_sigprocmask(SIG_BLOCK, NULL, [RTMIN], 8) = 0 read(0, <unfinished ...> <snip> and this strace end comes from csh: <snip> rt_sigprocmask(SIG_SETMASK, [INT RTMIN], [INT RTMIN], 8) = 0 close(0) = -1 EBADF (Bad file descriptor) dup(19) = 0 fcntl64(0, F_SETFD, 0) = 0 close(1) = -1 EBADF (Bad file descriptor) dup(17) = 1 fcntl64(1, F_SETFD, 0) = 0 close(2) = -1 EBADF (Bad file descriptor) dup(18) = 2 fcntl64(2, F_SETFD, 0) = 0 pipe([5, 6]) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [INT RTMIN], 8) = 0 fork() = 5991 gettimeofday({1060688761, 435762}, NULL) = 0 rt_sigprocmask(SIG_SETMASK, [INT RTMIN], [INT CHLD RTMIN], 8) = 0 close(6) = 0 read(5, <unfinished ...> <snip> and this strace end comes from xterm: <snip> close(4) = 0 close(4) = -1 EBADF (Bad file descriptor) rt_sigprocmask(SIG_BLOCK, [INT CHLD], [CHLD RTMIN], 8) = 0 fork() = 5967 rt_sigprocmask(SIG_SETMASK, [CHLD RTMIN], NULL, 8) = 0 close(3) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [CHLD RTMIN], 8) = 0 rt_sigprocmask(SIG_SETMASK, [CHLD RTMIN], NULL, 8) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [CHLD RTMIN], 8) = 0 rt_sigaction(SIGINT, {0x8076710, [], SA_RESTORER, 0x40051c68}, {SIG_DFL}, 8) = 0 waitpid(-1, [WIFEXITED(s) && WEXITSTATUS(s) == 0], 0) = 5966 waitpid(-1, <unfinished ...> <snip> The launch operation for programs like xterm, csh can be interrupted with CTRL-C, but when I run bash - I get the following errors in strace and the process won't terminate when I press CTRL-C: <snip> close(3) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [CHLD RTMIN], 8) = 0 rt_sigprocmask(SIG_SETMASK, [CHLD RTMIN], NULL, 8) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [CHLD RTMIN], 8) = 0 rt_sigaction(SIGINT, {0x8076710, [], SA_RESTORER, 0x40051c68}, {0x8087030, [], SA_RESTORER, 0x40051c68}, 8) = 0 waitpid(-1, [WIFEXITED(s) && WEXITSTATUS(s) == 0], 0) = 5944 waitpid(-1, 0xbfffe358, 0) = ?
