For a few exports, I get error pages:

Shall I make a bug, or is this already known?

I don't think we have a bug report for this yet.

Perhaps I've seen this or similar issue before (not sure) and we need to investigate.

Hm, very interesting. Just a try to analyze the problem:

Actually this is a 503 HTTP Error. It seems to be a temporary problem which would be the result for all wikidata-items.

But as you wrote it, it sounds as it was a problem with specific items, not affecting all. An error in the script, on the other side, would result in an 500-error, not 503.

Therefore I think there may be a problem in the server-side script resulting in something like indefinite loops. This is only executed for some specific items, not all.

For those Apache doesn't get a response in time from the script-engine, therefore it thinks that it is not responding at all – witch results in 503 – Service Unavailable.

Cheers.
