My understanding of the root of the problem is not the best, but I believe this is because of how Linux does locking. Typically, this should *only* happen if a process obtains a lock but crashes before it can be released. Otherwise, a well-behaved httpd server will not have this issue - it is quite good at cleaning up after itself. -- Daniel Ruggeri --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
