Using Linux-Firebird with some Java applets shows this effect, i.e. completelly bogging down X to a unusable state. Also, it's very easy to archive if you stress some ata-disks. In particular, if I copy a big (1 GB) file from ad0: 114473MB [232581/16/63] at ata0-master UDMA100 to ad2: 57259MB [116336/16/63] at ata1-master UDMA100 or vice versa, X will completely unresponsive until the the copy is finnished. A same kernel with the 4BSD scheduler doesn't show this, so I don't think it's hardware related. Alex
