My best guess is that you have circular links (soft or hard) somewhere in the main executable.

Ok still having problems.
Compiling fine within eclipse.
Ant working for compiling and installing own frameworks.
Ant fails with too many open files when building main executable. Occurs with a random framework. Can't open info.plist.
Have increased kernel parameters per process and total to x100 more than defaults - it just takes longer to fail. Feels as if woproject build steps is doing something wrong -recursion?
May have to downgrade to java16 and an earlier eclipse. What are people running generally at the moment?
Any help / pointers / ideas gratefully received!

Fixed this.
For any future readers - doing these steps fixed it (but I’m not sure what exactly solved it).
Clean everything
Delete local frameworks /Library/WebObjects/Versions/WebObjects543/Library/Frameworks
Rebuild wonder
Check all class paths for all homegrown frameworks and application and fix problems.
Move local project based frameworks so listed in dependent projects rather than external libraries.
Check correct wolips.properties file listed in eclipse preferences.
Delete spurious wolips.properties definition from project’s own build.properties that point to wrong wolips.properties files.

Thanks Fabian. Have tried that but get the error. Odd thing is that it happens so quickly; almost as if there is recursion. It seems to randomly throw this error on different frameworks each time I build.

Hi Mark,
Have you tried a reboot? Maybe you've somehow managed to exceed kern.maxfiles or kern.maxfilesperproc?

I’ve upgraded to java8, eclipse4.4 and latest Wonder.
Can compile and run from within eclipse but command line ant build failing with “too many open files”.
Has anyone encountered this error? Rather stuck - have tried cleaning and re-cleaning and re-installing wonder frameworks.
