Peter,
The behaviour of the WMSs is mysterious. I've had little luck
characterising the the issues, but here's three of the things I've seen
over the last few months:
Some WMSs working well (e.g.
https://svr022.gla.scotgrid.ac.uk:7443/glite_wms_wmproxy_server and
https://svr023.gla.scotgrid.ac.uk:7443/glite_wms_wmproxy_server) while
you have to wait forever for jobs to got through others
(https://lcgwms01.gridpp.rl.ac.uk:7443/glite_wms_wmproxy_server,
https://lcgwms02.gridpp.rl.ac.uk:7443/glite_wms_wmproxy_server ).
WMSs at the same site never working for me whatever I send
(lcgwms01.gridpp.rl.ac.uk,lcgwms02.gridpp.rl.ac.uk), while another at
the same site (cgwms03.gridpp.rl.ac.uk) works flawlessly. The
troublesome WMSs work OK for other users.
With WMSs submitting jobs to a CREAM server, the jobs starts, finishes
and awaits collection that never happens.
There is some evidence that the WMSs are the weak link, because it is
the same WMSs that crop up, while others work properly end to end. I've
no idea whether this is related to the problems seen by Kashif, but I
hope it helps.
