Sorry for late response...
I can see a difference in my and your setup. My hrSWRunTable short "httpd" as name of the httpd process, your shows "/usr/sbin/httpd"
Try using "proc /usr/sbin/httpd 30 1" in your snmpd.conf as a workaround.
And yes, please provide the strace, I want to see where the difference comes from.
