Whatever it was, it took some time to fix; somebody on airliners.net posted this:
The aircraft, of of KLM's B744 full passenger versions, registered PH-BFG, took off from SFO and somewhere around Sacramento the crew decided to turn back to SFO because the nosewheel wouldn't retract. The aircraft dumped fuel and landed safely at SFO. The flight was then delayed for 25 hours and on Monday, two KLM B744s will be taking off from SFO within an hour, yesterday's PH-BFG and Monday's KL606, likely to be operated by PH-BFB (subject to change).

Re fuel dumping, seafood issues, etc: I was always under the impression that jet fuel evaporated fairly quickly when dumped to the point where it was unlikely to cause pollution on land or sea (not sure about the atmosphere). Any comments re this?

You are correct, that is what I heard too, or probably read somewhere...
However, if you dump at low level, in a holding pattern, I remember being recommended to do it with a slight climb (200 fpm?), if you do 1 minute legs, so as to not come back into your own "evaporated" fuel... Generally, ATC tells you where to go to do your dirty stuff... I cannot recall where it would be for SFO, probably overwater.

Perhaps another thing they considered in the dump/no-dump decision was being unable to raise the entire landing gear in the event of the proverbial engine failure during an overweight overshoot.
Performance-wise, that might be untested and therefore undocumented, leaving them wondering if it could climb away with the extra drag.
So: heavy, engine-out go-around, unable to retract all the landing gear....
Except for simulating it at altitude to see if it could, that might weigh heavily( oops, a pun) on their decision to dump.
