Red Hat Bugzilla – Bug 17374
Make hangs with large values of parallel jobs
Last modified: 2007-04-18 12:28:32 EDT
Standard RH6.2 distro with make-3.78.1-4.
Passing make a large number of jobs, either as "-j n" or as "--jobs==n"
will hang make for large values of "n". The magic number appears to be
4098 on my test system. "make -j 4097" works correctly. "make -j 4098"
Note that make itself hangs - this isn't a problem with trying to spawn
too many processes. Make will hang even when all targets are up-to-date.
It fills up the pipe it uses (one character from each job, 4096
byte standard pipe buffer.)
Still present in 8.0 - make should be erroring this
