Oleg,
Thanx for the offer. I may take you up on it in the future but I was able to take a look at the log files and see problem. Just like you said the majority of the links being indexed after the 3rd link level were "noise content" tell a friend, search, email the advertiser, etc. I just pulled the link depth back to the point where the noise content began. I was able to set the ;Resource Limits; in php.ini back to the defaults and index the site in under a minute, capturing all the relevant links. It makes me wonder if a lot of the problems with memory errors and the program stopping I've been reading about in the forums aren't being caused by not limiting the content the program is allowed to scan. Thanx for you help and by the way, nice job with the program.
Thanx,
Scott
