First off the fix for vb 3.8.2 as the group changes break the base code:-

                ");
                $pcount = ceil($tcount['cnt']/$vboptions['vm_perpage']);

Next up we are getting a load of garbage in our sitemap even the zcat cant read the files:-

sh -c ' for i in *.gz; do echo $i; zcat $i | head; done' > 1
zcat: sitemap_21.xml.gz: trailing garbage ignored
zcat: sitemap_24.xml.gz: trailing garbage ignored
zcat: sitemap_27.xml.gz: trailing garbage ignored
zcat: sitemap_30.xml.gz: trailing garbage ignored

zcat: data stream error
zcat: sitemap_39.xml.gz: uncompress failed
zcat: sitemap_42.xml.gz: trailing garbage ignored
zcat: urllist.txt.gz: not in gzip format

Even some of the files that can be decompress are corrupt internally with invalid xml e.g. the data of the lastmod appearing in the url and missing close tags all over.

Has anyone seen this sort of corruption before?
