Hi all,

So I've been able to resolve the remaining issues with the data loader (thanks AndyS for your help) for integration tests in multi-node and cases 1, 2, 3 and 5 are now working. For case 4 however the last query fails (query 0030_largeResult.sql). The czar log gives the following (full logs available on dbdev1 at /usr/local/home/vaikunth/qserv-run/var/log/):

I am not sure if this is related to what Fabrice is seeing at in2p3, but when I run a simpler version of the 0030_ query myself I get (with error log also in the same location as mentioned above):
