This server crashed once already: T175973 so I believe a full rebuild is probably a good idea.
As I have to build a couple of hosts for s5 on Monday, I will rebuild this one too.

Same on db2023. Tag summary is not a reliable replicated table- it has differences on every wiki we checked (See other tickets checking inconsistencies between servers). That is most likely not a server issue but a query issue.
