One of the machines I use regularly has a nasty habit of suddenly locking completely (it happens maybe a couple of times a month). It's always when X is running, and, I am nearly sure, always when a browser is being used. This is a Debian testing system, running kernel 2.4.23. Mozilla-Firefox is the browser that is mostly used.
It's not just that X freezes; the whole system becomes autistic. In this state, it can't be reached from the network (no ssh, no ping, no nothing). The only way out, as far as I know, is with the power-button. Ctl-Alt-Del produces no response. Nor does Alt-SysRq, which means, I suppose, that the kernel is dead. These events leave no trace whatever in the logs and so it's frustratingly hard to do any useful trouble-shooting. I thought that they might be caused by a corrupt memory-module, and so I ran memtest for the best part of a day. However it found no errors. I know that this much doesn't provide a lot of information to go on, and I apologize for that. But does anyone know of ways to work on a problem such as this? I'd be really grateful for any tips or pointers. Jim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
