bash: fork: Permission denied -- how can I fix this?

[James Adams]

I have recently installed Cygwin version 2.510.2.2 onto a Windows XP system and when I launch it the first thing I see is this:

      5 [main] bash 3024 fork: child -1 - CreateProcessA failed, errno 13
bash: fork: Permission denied

I get the same message when I try running the ls command:

bash-3.2$ ls
9404505 [main] bash 1544 fork: child -1 - CreateProcessA failed, errno 13
bash: fork: Permission denied

Can someone suggest what's going wrong, and how I can fix it?

Thanks in advance for any help.

2.510.2.2 is the version of 'setup.exe', not Cygwin.  The Cygwin package,
which is just one of many in the Cygwin distribution, is currently 1.5.24-2.

OK sorry, the Cygwin version is 1.5.24-2

Let's start here: <http://cygwin.com/problems.html>

The only thing listed on that page that I didn't do was to include the output from cygcheck, since cygcheck also gives the fork permission denied error:
 
bash-3.2$ cygcheck -s -v -r > cygcheck.out
69675674 [main] bash 3156 fork: child -1 - CreateProcessA failed, errno 13
bash: fork: Permission denied

cygcheck is a Windows program so you can run it from a cmd.exe prompt.

You'll just have to make sure you use the full path or go to your
cygwin\bin directory first.

I fixed the problem by installing into another directory other than C:\cygwin.  I have no idea why this fixes the problem, but probably it has something to do with security packages installed on the computer (it's a new work laptop which appears to have several security related programs installed on it by corporate IT).

Thanks Jason, it wasn't clear that cygcheck was a Windows program, although it makes perfect sense (if Cygwin isn't working then it's not likely that you'd be able to execute a program from within it).

  It might be worth checking the http://cygwin.com/acronyms#BLODA.  I owe
Cygwin 1 FAQ entry for this, in the meantime the latest version of the list
can be seen at

Hi, I had this same error, and recovered by moving c:\cygwin to c:\cygwin.some_other_name, then reinstalling the entire cygwin pretty much as I had it before.

So, in my case at least it doesn't seem to be security; just a "reinstall from scratch" type of thing.

I had noticed that for the past few weeks, it had been taking longer to bring up a cygwin bash window than before; otherwise it appeared to be fine.  Now, the bash shell comes up instantly as it had prior to a few weeks ago (so, this oddity is now gone too).  

What I had done during those weeks was, gradually install a few packages that I hadn't previously (ssh, ccrypt, probably a few others I can't remember).  The twist was, I do this (download and install) on two machines.  The cygwin install directory is on a portable hard drive; as I download new packages to it on a couple different machines, I install them on both machines as I reconnect the drive to them.  Oh, also, this installation folder is Really Old; probably at least 3 years old (and I've upgraded it to new cygwin versions at least twice).

My version info from cygcheck --sysinfo is:

 1830k 2007/01/31 C:\cygwin\bin\cygwin1.dll
    Cygwin DLL version info:
        DLL version: 1.5.24

Anyhow, I figure that something went bad; reinstalling has fixed.  Going on my merry way.
