Fatal error when try to generate sitemap

After updating to vB3.8.0 Final, when ever I try to run the sitemap generator via Scheduled Tasks or Sitemap control panel I'm getting this fatal error..

Code:

[SECTION START] tags [9,051.0Kb mem used] [2,148,610s (+163s)]
[create sitemap file] filename: sitemap_7.xml.gz, number of urls: 11774 [9,056.6Kb mem used] [2,148,612s (+2s)]
[create sitemap in text format] part #8 [9,056.6Kb mem used] [2,148,612s (+0s)]
[create sitemap index] filename: sitemap_index.xml.gz, number of sitemaps: 7 [9,057.7Kb mem used] [2,148,612s (+0s)]

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 42418957 bytes) in /home/xxxxxxx/public_html/vbseo_sitemap/vbseo_sitemap_functions.php on line 1299

I'm using vBSEO sitemap generator v2.2 and my server's PHP memory limit is 32.00 MB.

So I've to Increase PHP memory limit ?

Yes, you will need to increase your memory limit.

Are there any other options than to increase the memory?

Aside from lowering the amount of work required for the server to do (by removing elements from the sitemap prior to generation), no... if you are receiving 'out of memory' errors, you will need to increase the available memory.
