we had this problem with our buggy CX here, too. I thought that the CX
had some issues, but now I start to think that's a fault on the kernel side.

If anybody is interested - as the buggy CX will be replaced, we're
moving our production data to a different storage until we have the new
machine. The old one will be used as additional disk-to-disk backup, but
I can't see there any problems in testing/debugging stuff with it. At
least I can put it under heavy load and see what will happen.

Any ideas on that?
