I'm presuming this is new behaviour on 1.19wmf1?

The community reported this error only after the upgrade.

I did some other moves and they didn't trigger 500, so more specifically, one of those problematic pages is [[Android Market]].

The first line would be useful also

Has this been seen since? I'm bumping milestone, but I imagine it could be closed as fixed.

This particular page is movable now but the moving action is still somehow slow. Since this is an OOM error I would imagine there's still something expensive happening.

Liangent: Is this still slow?
Wondering if this is really MediaWiki code related or WM some server issues...

I forgot how slow it was, but now it takes 9s to move (observed in Firebug). Looks similar to its rendering time (<!-- Served by mw1087 in 6.769 secs. -->).

Hmm, sounds sufficient to me.
Going to close this as WORKSFORME soon if nobody complains.
