[MediaWiki-l] Scribuno / Lua problem

I have hit a problem with the Scribunto extension which, after a good
few hours digging,  I have not been able to  track down and fix. It
manifests as an 'Internal server error' with the message ' The server
encountered an internal error or misconfiguration and was unable to
complete your request.' , but only when completing or previewing an
edit. All affected pages still work fine except that their main template
cannot be edited (The pages themselves can).

The site uses about a dozen big and complex Semantic templates, each
including up to twenty additional templates plus calls to the standard Wikipedia
'infobox' Lua module. Trying to complete or preview an edit to that
module separately produces the same error aswell.

I can find no related entries in the http error or any other log and the
Infobox module last edit date predates this problem by at least a year.
It therefore looks to me like a Linux server config issue of some sort,
although I cannot recall any changes there that pre-date the problem either.

Can any one offer any ideas please.
