It seems like the sitemap is actually being created fine and it is only the part of sending you the confirmation email that is failing... 121seconds to generate 45 sitemap files is actually quite a reasonable time, though it may be that your mySQL is timing out because of this time so you need to increase the mySQL wait timeout to something a little higher.

Or you can change sitemap generator settings like this thread : vBSEO Sitemap Generator : Quality vs Quantity
You will avoid any problem with sitemap after changing these settings.

It looks like you are including your archive pages, especially. You should disable that setting. It will cut your file count in half.
