Hi, When you refer to client-nodes, you mean mysqld's, right? I guess that this is a memory/swapping problem, i.e you mysqldump-script causes mysqld to allocate lots of memory, causing ndbd to be swapped out. And ndbd being swapped out, is a almost certain way of causing WatchDog to "fire". Could this be correct? Can you also upload your config.ini /Jonas
