We have an existing website running on Azure with quite a large examine index all been working fine for over a year. We recently upgraded to 7.3.4 now over last week we have had 2 issues which have been pinned down to indexes.

We have a board and that lists a load of items that come from an examine search. Since the upgrade that board sometimes is empty. We do not see any errors in umbraco log. When we rebuild the external index after a while the board starts working again.

Has anyone seen this before?

Regards
