Modified: conf httpd.conf-dist
src Configure
Log:
Some kernels refuse to setgid(group) or semctl(IPC_SET) when the group
number is above 60000. The Apache Default of #-1 is interpreted by these
kernels as a huge positive integer, and semctl() fails with EINVAL.
A NOTE was added to the httpd.conf-dist file to warn about such a problem.
I was mislead into thinking that ReliantUNIX had semctl() problems, but
the reason was a wrong group id; the ReliantUNIX 5.44 fallback to
USE_FCNTL_SERIALIZED_ACCEPT was therefore unnecessary, I reverted to the
old default.
