Lots of swap space exceeded warnings, 20k++ active processes and I had to stop-A the system. Even reducing the number of clobber builds to 6 at a time left several of them with "errors" due to resource allocation failures: dmake: Fatal error: Could not fork child process for dmake job: Resource temporarily unavailable And after 9-10 hours, too. Short answer - add more swap, and only do one build at a time. :-) Cheers, James -- Senior Kernel Software Engineer, Solaris Sun Microsystems http://blogs.sun.com/jmcp http://www.jmcp.homeunix.com/blog _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
