When I run cygwin, I sometimes run into the following error, e.g during compiling.

I only have 1 cygwin open. And I have kill all other windows program. I have 4GB memory.

....      1 [main] sh 7508 fork: child -1 - forked process 4868 died unexpectedly, retry 0, exit code -1073741819, errno 11
/bin/sh: fork: retry: Resource temporarily unavailable

Is there anyway to fix this problem?

Thank you.

Sounds like you have insufficient installed memory to support your application, cygwin, windows, and your other programs and services running on your system.

Usually this means that you

  • have some incompatible software installed on your computer, or
  • some installed libraries are not updated properly, so you need either update them using Cygwin setup, or Rebaseall them when no cygwin processes are running.
