Indexing is not working for distributed search

[cjmyers]

Indexing is failing when fetching information from synbiohub.org/?sparql instance.

Error Virtuoso S1T00 Error SR171: Transaction timed out is being thrown on the query:

SPARQL query (querying for links):

SELECT DISTINCT ?parent ?child
WHERE
{
    ?parent sbh:topLevel ?parent .
    ?child sbh:topLevel ?child .
    { ?parent ?oneLink ?child } UNION { ?parent ?twoLinkOne ?tmp . ?tmp ?twoLinkTwo ?child }
}

Reaches an OFFSET of 560,000 and 590,000 on two machines that I tried running indexing on (with distributed search turned on).

Looks to be fixed for now; will reopen if issue arises again.

EDIT: Looks like it is now hanging when queryling by parts. Additionally, synbiohub.org seems to be indexing by graph, may not be on the latest commit.
