Hi ,
          We are running mysql -4.0.18 on Tru64 5.1A pk4 trucluster .
Yesterday we were dumping some data out and the whole cluster froze .
The system spewed out only the following console messages and ofcourse froze.

No logins were possible either from console or through ssh .
Only way to come out this frozen situation was to press the Magic Button :( .

I know there is not much of info, But there is something ;)
Any pointers to see where the problem is .

Specs for the Cluster

2 hard partitioned QBBs of GS320 .
8GB RAM - 4 x 733 MHz CPU .
Trucluster on Ethernet .

Thanks in Advance
