All of a sudden, I now noticed that my sitemap is not building and it states the following:
# 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 13.49MB, the limit of your server is 40M.
# The last known execution time of the script was 0.46 seconds, the limit of your server is 50000 seconds.
# The script stopped around post number 394 (+/- 100)
When I manually try to build it, it just displays a blank page and when I return to the main page it just gives me the above errors. I am nowhere close to my server limits as stated above. This seemed to just start happening for no reason.
