New description:

 When uploading a file, it fails with the following error:

 <class 'allmydata.interfaces.!UploadUnhappinessError'>: shares could be
 placed on only 4 server(s) such that any 3 of them have enough shares to
 recover the file, but we were asked to place shares on at least 5 such
 servers. (placed all 5 shares, want to place shares on at least 5 servers
 such that any 3 of them have enough shares to recover the file, sent 6
 queries to 6 servers, 4 queries placed some shares, 2 placed none (of
 which 2 placed none due to the server being full and 0 placed none due to
 an error))

 There are 12 servers connected to this grid (pubgrid) yet 6 queries are
 send, and because two are full the upload fails (if i interpreted the
 error right).

 Shouldn't there be another round of queries if the first round does not
 yield enough available servers?
