I am just curious (a) if this is a widespread problem (which I doubt,
since I haven't heard about it) and (b) if it is, what's the ETA for a
"Here's how this works: if you have a disk with many writes and reads,
system hasto queue these. If you have a big queue, or heavy load, the
appears when you have writes trying to happen before reads. The
programs needing to
read will be stopped until the queue flushes. Or, if you don´t
necessarily have a
big queue, the problem can appear from deadlock resulting from a
"kjournald" waiting for a system call when there is a particularly long
request in the queue. So, all programs depending on the kjournald
process begin to
wait for kjournald to commit its writes, which never really happens,
programs begin to cascade into an "uninterruptible sleep" state, and
begin to stop.
In theory, if you wait, your system can return, but this can be a long
significant downtime. None of us can wait, and the only solution is to
