Solving WordPress 18.104.22.168 Trackback and Pingback Sending ProblemsBy Angsuman Chakraborty, Gaea News Network

I was unable to send trackbacks and pingbacks after I tested with WordPress 22.214.171.124. I found the solution yesterday.
I had too many XMLRPC Ping servers on my list and the php process was timing out while still pinging to them and before it could execute the trackback/pingbacks associated with the post.
The obvious solution is to reduce the list of servers you ping. I adopted a different approach. I increased the timeout to 5 minutes instead.
BTW: Check your pingback/trackback sending ability at Pingomation.
Let me know if it addresses your problem.
