• StoRM v1.3 SE (lcgse02.phy.bris.ac.uk) is still SL4 as is its slave gridftp server gridftp01.phy.bris.ac.uk. StoRM v1.4 & 1.5 are not supported on SL5, and StoRM v1.6 & 1.7 (supported on SL5) are very unstable & not production ready yet (just ask Chris Walker who's had ++painful experience with them). Waiting on stable StoRM for SL5 - soon hopefuly.
  

• lcgnetmon (owned+operated by RAL) is still SL4 AFAIK
