Rebaseall and peflagsall were running. We have this error really not reproduceable on some compile machines. These machines are running a perl script which polls a remote database for running make jobs in parallel (-j flag) - that's all. Normally all works fine - but sometimes we got these fork errors. Is there an possibility to get more information who is occupying the address space? Perhaps I can instrument the cygwin1.dll to wait or do something special - so I can use other tools i.e. sysinternals vmmap, process explorer ... to have a look who is using this address space. Perhaps a self build debug snapshot version with instrumented debug flags will give me some hints? Please - can anyone give me some hints. Any help is welcome. best regards Heiko -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
