(It's working for regular activity.) Additionally, the region server is now using all the CPU on the host, running all 8 cores at 100%. I've got several jstacks, they all look like this: http://pastebin.com/dGTmTEN7 If I do a wget of the /jmx url, it starts responding, but never completes, always stopping at the same point: http://pastebin.com/qhNvxrQK Has anyone ever seen this before? If so, Is there a way out of it? (other than bouncing the region server). BTW: There's nothing relevant in the region server log and the garbage collector log is normal. ---------------------------------------------------------------------- Ron Buckley
