Does anyone else experience the behavior where a client crashes and takes out the mds at the same time? I have the lustre filesystem mounted an an administrative PC so I can keep an eye on it, but if that machine ever becomes wedged (all too common) and requires the sysrq-s,u,b treatment, the mds crashes immediately. Seen on 1.2.4 with SLES9. Perfectly reproducable. -jwb
