Thank you for the reply. Yes, micro seconds and inode number. Wondering the probability of hitting the same queue id on one server after a time correction, or probability of hitting the same queue id on multiple servers. Thinking about it, it should be quite low and on par with basic hashing functions, but I was not able to do the math. From your answer I guess I shouldn't look any further and just add the hostname behind the queue id. But, on that note, adding a single random character would have probably made it as good as many hashing functions. Thanks again -- Mehmet
