Simplistically, they are files used by Apache to control
exclusive access to some resources.

Don't delete them.

Thanks. Read it and know about as much as before.

"The LockFile directive sets the path to the lockfile used when Apache =20
is used with an AcceptMutex value of either fcntl or flock."
??
Can someone please translate that into plain English?
I'm not a seasoned sys admin, just a user running Apache on my desktop =20
for web development. The way I read that, it describes a =20
"directive" (a config command?) that is used to create those lock =20
files. But it doesn't explain what those lock files are and why they =20
are needed in the first place.

I searched the net but couldn't find a good explanation. Would =20
appreciate any more hints or links.

Thanks,
Steven
