UCSC upload error

[migs54]

Has anyone seen an error like this while trying to upload a bedgraph.gz to UCSC:

Warning/Error(s):

Can't start query:
select genome from dbDb where name = 'hg19'
mySQL error 2013: Lost connection to MySQL server during query

My bedGraph.gz is 283MB

head hESC.bedgraph

track type=bedGraph name=hESC
chr1 14388 14398 1
chr1 14398 14402 2
chr1 14402 14438 3
chr1 14438 14448 2
chr1 14448 14452 1
chr1 14586 14636 1
chr1 14702 14703 1
chr1 14703 14705 2
chr1 14705 14712 3

The genome was already selected as hg19 so I'm not sure why that shows up in the error message.

Any suggestions welcome!

Thanks
