I had writen 3 help posts ealier, but all went answered. I'm in urgent need of expert advise on the following issue at this moment.
WordPress is generating "do_pings cron" with each new posts that I'm publishing, but I don't know why the cron is not initiating, and all cron jobs are continue pending in options table.
If I manually run wp-cron.php, it works, and sometimes generates 404. But it's not initiating automatically.
I've run fsockopen test, and it's give success, DNS test are also passed.
Last week, DreamHost tried to disable wp-cron.php as it was genertaing huge spikes, but that completely bogged down the server.
May I request for expert advise to troubleshoot this issue. At this moment, I'm deleting cron jobs in options table for the last two days to keep the site running.
