    118118== [http://rt.dcache.org/Ticket/Display.html?id=5490 RT 5490]: kerberos, encryption == 
    119119 
     120Right solution is to get the right security provider for these algorithms. 
    120121 
     122Alter the ktab file on the server so it doesn't use a security algorithm that Java doesn't support out-of-the-box.  DESY sys-admin people rejected this solution.

    122124== [http://rt.dcache.org/Ticket/Display.html?id=5502 RT 5502]: Peculiar problem == 
     125 
     126Paul & Tigran to investigate further.

    123128== [http://rt.dcache.org/Ticket/Display.html?id=5518 RT 5518]: Re: "No write pools configured" error == 
     129 
     130Configured two linkgroups with the same parameters, each with a single link.  User can write into one link(-group) or the other.  One succeeds and the other fails. 
     131 
     132The issue comes because space-manager doesn't know into which link the user's write request will end up, as the PoolManager makes that decision.  This is an architecture issue. 
     133 
     134If we don't need to fix this tomorrow, we are slowly moving towards distributing functionality from PoolManager to other components and making it more module.  This may allow space-manager to run a pool-manager inside. 
     135 
     136For now the sites can live with the current behaviour. 
     137 
     138Keep ticket, but don't need to discuss in team meeting any longer. 
     139 
     140Think about passing PoolManager an order list of linkgroups and poolmanager chooses one. 
     141 
    124142== [http://rt.dcache.org/Ticket/Display.html?id=5523 RT 5523]: transfer failures "No transfer markers received for more than 120 seconds" == 
     143 
     144One possible explanation is that checksumming is taking too long.  When there's no mover any more, the door send no further transfer markers.
