# The last run didn't finish! Maybe you can raise the memory or time limit for PHP scripts. Learn more
# The last known memory usage of the script was 14.5MB, the limit of your server is 128M.
# The last known execution time of the script was 13.12 seconds, the limit of your server is 600 seconds.
# The script stopped around post number 1514 (+/- 100)
Now see i have given 128 MB memory and 600 execution time and server is not busy at all. It can't generate 15000 posts sitemap. Please help me.
