About thirty minutes ago I started an update. Everything downloaded fine. But when it came to "Running Transaction", it hung: .... Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Updating : xulrunner 1/18 And there it sits still. There's plenty of disk space. The load on the CPU is under 1.0. There is some disk activity, but no way so much as to cause anything to hang and no major writing related to yum. Disk reads are just about null, except just now when I grep'ed for something to make sure that the disk could be read. I'm not using even half of the available RAM. Anyone else run into this problem?
