I have detected a strange issue with IPv6 and mmap in Windows XP. I want to execute varnish program from windows cmd.exe, launching a BAT file. If IPv6 is deactivated (default in windows xp) all works OK.
But if I activate IPV6 with following comand: C:\WINDOWS>netsh netsh>interface netsh interface>ipv6 netsh interface ipv6>install (and reboot) Varnish stats to fail only if it is launched from windows cmd.exe, the error is on fork: 77 739 [main] varnishd 9212 ********************************************** 59 798 [main] varnishd 9212 Program name: C:\apps\varnish 2.1.4\bin\varnishd.exe (pid 9212, ppid 1) 58 856 [main] varnishd 9212 App version: 1007.8, api: 0.0 55 911 [main] varnishd 9212 DLL version: 1007.8, api: 0.235 56 967 [main] varnishd 9212 DLL build: 20110114 14:59:29SNP 58 1025 [main] varnishd 9212 OS version: Windows NT-5.1 55 1080 [main] varnishd 9212 Heap size: 402653184 55 1135 [main] varnishd 9212 ********************************************** 58 1193 [main] varnishd 9212 pinfo::thisproc: myself->dwProcessId 9212 114 1307 [main] varnishd 9212 child_copy: dll data - hp 0x670 low 0x6115E000, high 0x61166DA4, res 1 18939395 18940702 [main] varnishd 9212 child_copy: dll bss - hp 0x670 low 0x611DA000, high 0x6120E8D8, res 1 539 18941241 [main] varnishd 9212 child_copy: user heap - hp 0x670 low 0x520000, high 0x590000, res 1 66 18941307 [main] varnishd 9212 child_copy: done 31834 18973141 [main] varnishd 9212 child_copy: data - hp 0x670 low 0x446000, high 0x458BAC, res 1 237 18973378 [main] varnishd 9212 child_copy: bss - hp 0x670 low 0x45F000, high 0x470078, res 1 77 18973455 [main] varnishd 9212 child_copy: done 77 18973532 [main] varnishd 9212 fixup_mmaps_after_fork: fd -1, h 0x678, address 0x60FA1000, len 0xF000, prot: 0x4000003, flags: 0x31, offset 0 149 18973681 [main] varnishd 9212 MapView: 0x60FA1000 (status 0x0) = NtMapViewOfSection (h:678, addr:60FA1000, len:61440, off:0, protec t:40, type:0) 98 18973779 [main] varnishd 9212 fixup_mmaps_after_fork: fd 4, h 0x674, address 0x5BF90000, len 0x5010470, prot: 0x3, flags: 0x1, offs et 0 105 18973884 [main] varnishd 9212 build_fh_pc: fh 0x6124289C 68 18973952 [main] varnishd 9212 MapView: 0x0 (status 0xC0000018) = NtMapViewOfSection (h:674, addr:5BF90000, len:83952752, off:0, pro tect:40, type:0) 18974019 [main] varnishd 9212 fhandler_disk_file::fixup_mmap_after_fork: requested 0x5BF90000 != 0x0 mem alloc base 0x0, state 0x10000, s ize 12451840, Win32 error 487 67 18974019 [main] varnishd 9212 fhandler_disk_file::fixup_mmap_after_fork: requested 0x5BF90000 != 0x0 mem alloc base 0x0, state 0x10 000, size 12451840, Win32 error 487 18974448 [main] varnishd 9212 C:\apps\varnish 2.1.4\bin\varnishd.exe: *** fatal error - recreate_mmaps_after_fork_failed 429 18974448 [main] varnishd 9212 C:\apps\varnish 2.1.4\bin\varnishd.exe: *** fatal error - recreate_mmaps_after_fork_failed Stack trace: Frame Function Args 0023E5A0 6102771B (0023E5A0, 00000000, 00000000, 00000000) 0023E890 6102771B (6117CC40, 00008000, 00000000, 6117E997) 0023F8C0 61004E3B (6117EDCC, 00000000, 6117EDC6, 00446000) 0023F900 610060D1 (000007D0, 02000000, 61168704, 61168700) 0023F930 610063E0 (00000000, 00000002, 00000000, 00000000) 0023F9F0 6106EA75 (61000000, 00000001, 0023FD30, 6106E7C0) 0023FA10 7C90118A (6106E7C0, 61000000, 00000001, 0023FD30) 0023FB18 7C91C4FA (0023FD30, 7FFDF000, 7FFDA000, 00000000) 0023FC94 7C9211B4 (0023FD30, 7C900000, 0023FCE0, 7C90E900) 0023FD1C 7C9210AF (0023FD30, 7C900000, 00000000, 00010017) End of stack trace If I execute varnish from bash, it works fine. It seems that the problem is produced in "NtMapViewOfSection" windows function. Somebody has the clue why it only fails when it is launched outside bash and with IPv6 activated???
