That makes sense.
Sorry, SCHED_BATCH is unique to my tree at the moment so this is my mistake for not considering it. I'll have to transiently schedule SCHED_BATCH tasks as SCHED_NORMAL if we are going into swsusp. It's something I'll have to work on. In the interim, a workaround would be to convert all httpd threads to SCHED_NORMAL before shutting down in your scripts somewhere and convert them back after resuming.
Cheers, Con
