              Tickets: 3 still open, only 1 still relevant

              - 142370 was likely not AGLT2-specific and resolved by dCache update.
               We think this ticket can be closed

              - 143505 transfer problems to  BEIJING-LCG2 and IEPSAS-Kosice
               two separate problems or symptoms. Transfer rates still bad.
               We had investigated the examples flagged in this ticket
               Beijing: No byte transferred. Not clear why
               Slovakia: 1h timeout on 7G file which would likely otherwise complete

             - 143575 errors from one particular WN which was rebuilt
               We think it should be closed

             Software:

               dCache updated to 5.2.6-1

             Hardware:

             - 2 of the new R740XD2 are in production and we are draining
               older storage for planned retirement

             - 4 Formulus Black Worker nodes are being installed for use with ForsaOS
               which will run 72 HTcores out of 512G of memory with nVME storage.
               We will compare 2 built with ForsaOS and 2 as "conventional" SL7.
               Those were purchased with UM Tier3 funds but will also run Tier2 jobs.
