Re: Bug #8889 Updated: Memory is not being freed.

Andi's statement is correct. I believed that but felt something else was wrong. Andi gave me the benefit of the doubt (yeah Andi!) and took a close look at the code. I asked him what he changed and he said: "The memory manager did some memory block caching which was causing very bad fragmentation. I fixed it so that it'll minimize memory fragmentation in between requests." So, good for PHP! Brian Moon ------------------------------------------ dealnews.com, Inc.
