Resource Temporarily Unavailable
Thu Sep 7 20:04:00 GMT 2006
Hello, I work at a company where we have a complicated Linux build. We
use cygwin to mimic this build on windows for some of our windows
At different times when cygwin forks it will throw a Resource
temporarily Unavailble error. I am tempted to call this "Random"
because it doesn't manifest itself until a random time, but once
manifested it will continue to fail at the exact same spot. This spot
is different for all users but once it does happen it continues to
This is typically in our make flow when it is forking or spawning
another process to execute a command.
Here is a snip
/usr/bin/env: ../../../../..//bin/Win32/cfp: Resource temporarily unavailable
makepp: Failed to build target gf100.xml
One thing to note, the command that it fails on is different for all
users. It actually fails when forking. Another example is
/usr/bin/bash: fork: Resource temporarily unavailable
make: *** [ObjWin32/.PTreeVisitor.d] Error 128
After looking at the cygwin source I found that EAGAIN which produces
this message is mapped to many windows errors. So after more
investigation I found it to be Win32 error 234 which is
ERROR_MORE_DATA. I then traced this down to when cygwin calls
CreateProcessAsUser in spawn.cc
So my question, has anyone seen this before. I don't think it is a
cygwin bug since it the win api returning this error, but maybe it is
something to do with the call.
Any pointers or tips would be helpful.
