Thread:Project:Support desk/Lua/Infobox Script Errors

I've just installed infoboxes and whatnot, and I'm getting jammed up with a big red Script Error on any pages that attempts to include them. Clicking the error gives me "Lua error: Internal error: Error reading from pipe," and the Lua error log gives me:

domains/hwc.tv/html/w/extensions/Scribunto/engines/LuaStandalone/lua_ulimit.sh: xmalloc: ../bash/subst.c:3503: cannot allocate 255 bytes (73728 bytes allocated)

The number of unallocated/allocates bytes varies depending on the page, attempts to edit, etc. Example is at http://hwc.tv/w/index.php?title=Template:Infobox

So far I've attempted changing the $wgMaxShellMemory to numerous values, from reasonable to absurdly high, and 755 permissions are set correctly. The engine is Luastandalone. I'm running out of things to change.
