The current git should not produce anything like >this (and does not, here). ... You are absolutely correct. My comrade ran this with 1.5.0.1 by mistake. He reran the strace with 1.5.3.5, and I have replaced the tarball on my server: http://www.zopyra.com/~rael/git/git-trace.tar.bz2 With this minor correction (!), here is the last part from the last file (strace.out.26001): [...] write(2, "\n", 1) = 1 write(3, "\335\365\205\262RY\360=^h\357\372\274\374_\177\317\357"..., 3712) = 3712 fstat(0, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0 open("/etc/mtab", O_RDONLY) = 4 fstat(4, {st_mode=S_IFREG|0644, st_size=503, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a955fa000 read(4, "/dev/sda1 / ext3 rw 0 0\nnone /pr"..., 4096) = 503 close(4) = 0 munmap(0x2a955fa000, 4096) = 0 open("/proc/meminfo", O_RDONLY) = 4 fstat(4, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a955fa000 read(4, "MemTotal: 16396892 kB\nMemFre"..., 1024) = 672 close(4) = 0 munmap(0x2a955fa000, 4096) = 0 write(2, "Resolving 562 deltas...\n", 24) = 24 rt_sigaction(SIGALRM, {0x40f610, [], SA_RESTORER|SA_RESTART, 0x32c512e2b0}, NULL, 8) = 0 setitimer(ITIMER_REAL, {it_interval={1, 0}, it_value={1, 0}}, NULL) = 0 pread(3, "", 242, 1268) = 0 write(2, "fatal: ", 7) = 7 write(2, "cannot pread pack file: No such "..., 49) = 49 write(2, "\n", 1) = 1 exit_group(128) = ? Sorry for the mistake. I think Linus once commented on an alarm that he found curious in a previous strace I sent for this some time ago ... Bill
