Hi, Since increasing the number of servers at RAL from 8 to 21 we seem to be seeing a new failure mode. All the processes seem to be running fine and you can read a file by going directly to the server that hold is but the server does not seem to respond via the olbd network so if you try to access a file via the load balancer you fail. Restarting the load balancer on the data server fixes the problem. There is nothing unusual in the logs at either end as far or anything missing either as I can tell. This is on data servers running RH73 and xrootd-20040907-0403 or xrootd-20041214-1142. Has anyone else seen this? Is there a fix? Thanks, Chris. -- Chris Brew ([log in to unmask]) +44 1235 446326 Particle Physics Department Rutherford Appleton Laboratory Chilton, Didcot. Oxfordshire. OX11 0QX. United Kingdom.
