SYS Holding onto Temporary segments

All,  

I had users complaining of select statements failing with "failed to extend temp segment" errors this morning. When I did a bit of digging around I noticed that SYS was holding onto 1 segment in the TEMP tablespace which was just under 15Gb (our temporary area almost full). I tried all the little tweaks (changing pctincrease to what it already was, coalescing etc) but to no avail, then about 5 minutes ago it released it all. Nobody was logged in as SYS.  

Is this a bug or is it my misunderstanding of how the temporary segments are used.  

TIA   PS. Thanks to all who responded to my RAID query.
