pipe error depending on drive

pipe error depending on drive

[DEWI - N. Zacharias]

Hi all,

I have a strange behavior of cygwin here. I have two machines with the nearly (*)he same configuration on machine A everything works good, on B I get the error

      1 [main] sh 1884 sig_send: error sending signal -40 to pid 1884, pipe handle 0x768, Win32 error 6
sh: fork: retry: Resource temporarily unavailable

depending on which drive I start a perl  program which uses a pipe via IO::File->new("dosomething.pl |");

 (*) On A Cygwin is installed in C:\Programme\cygwin and uses
 Cygwin DLL version info:
        DLL version: 1.7.9
        DLL epoch: 19
        DLL old termios: 5
        DLL malloc env: 28
        Cygwin conv: 181
        API major: 0
        API minor: 237
        Shared data: 5
        DLL identifier: cygwin1
        Mount registry: 3
        Cygwin registry name: Cygwin
        Program options name: Program Options
        Installations name: Installations
        Cygdrive default prefix:
        Build date:
        Shared id: cygwin1S5

on B in C:\cygwin
and uses the most resent version

  Cygwin DLL version info:
        DLL version: 1.7.15
        DLL epoch: 19
        DLL old termios: 5
        DLL malloc env: 28
        Cygwin conv: 181
        API major: 0
        API minor: 260
        Shared data: 5
        DLL identifier: cygwin1
        Mount registry: 3
        Cygwin registry name: Cygwin
        Program options name: Program Options
        Installations name: Installations
        Cygdrive default prefix:
        Build date:
        Shared id: cygwin1S5



On drive C: everything works fine but on the other drives e.g. H

Mount yields:

Machine A
C:/Programme/cygwin/bin on /usr/bin type ntfs (binary,auto)
C:/Programme/cygwin/lib on /usr/lib type ntfs (binary,auto)
C:/Programme/cygwin on / type ntfs (binary,auto)
F: on /cygdrive/c type ntfs (text,posix=0,user,noumount,auto)
H: on /cygdrive/h type nwfs (text,posix=0,user,noumount,auto)

Machine B
C:/cygwin/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (text,posix=0,user,noumount,auto)
F: on /cygdrive/f type nwfs (text,posix=0,user,noumount,auto)
H: on /cygdrive/h type nwfs (text,posix=0,user,noumount,auto)

Two other issues are also strange  :

First if I try to update machine A I get the warning that this is the first time that I setup version 1.7 (setup 2.774)
Second the /etc/fstab file seems to have no effect on the mountings on machine B
Even if I delete this file I get the same settings

Is there anybody out there who knows what is going wrong ??

Thanks
Norbert

More than 1 installation on this machine?  Check 'cygcheck -srv' output.

'/etc/fstab' is "additive".  Put additional mount points in this file.  The
ones you have are the defaults so they are not driven by this file.

[zac] In the meantime it turned  out that the fork fails only if the bash was started form a network drive.
If the bash was started from local drive there is no problem with fork even if one switches to a network drive after launching bash.

[zac] Nope!  And  it was not the first time I update Cygwin. The ones before work without such a notice.

[zac] Thanks and have a good time
