SPF endless lookup

I found the following SPF errors in my maillog:

Sep  7 14:59:57 i3way sendmail[28894]: r876xsvM028894: Milter add: header: Received-SPF: unknown (i3way.net: error in processing during lookup of domain of 8.h.dvosh.info: Mechanisms used too many DNS lookups) receiver=i3way.net; client-ip=173.254.227.52; helo=8.h.dvosh.info; envelope-from=gvr@8.h.dvosh.info; x-software=spfmilter 0.93 http://www.acme.com/software/spfmilter/;

On checking the TXT record of the domain, it includes itself for further looking up.  This will result in an endless loop.  Here is what I found that caused the many lookups:

[warren@dnssec ~]# dig txt 8.h.dvosh.info | grep spf

8.h.dvosh.info. 3555 IN  TXT "v=spf1 include:8.h.dvosh.info ~all"
