     17No issues to bring up.

     19Questions: 
     20 
     21Kinda planning for the 5.1 release next week at NDGF.  Any known issues: no. 
     22 
     23 
     24== KIT == 
     25 
     26Everything is running fine. 
     27 
     28=== http domain crashes === 
     29 
     30RT ticket 9537 
     31 
     32New possibility due to thread getting stuck. 
     33 
     34=== xrootd transfers failing === 
     35 
     36RT ticket 9648 
     37 
     38Installed latest client (v9.4.1) --  
     39 
     40Seen segmentation fault. 
     41 
     42Updated configured so it now dumps the core. 
     43 
     44Once there is a core dump, will contact the xrootd developers. 
     45 
     46=== ZK reconnection === 
     47 
     48RT 9676 
     49 
     50Update the ZK connection string to 
     51 
     525 minutes for the DNS timeout in Java, updated DNS record to point to the new ZK server, waited more than five minutes, then restarted the ZK server.  dCache reconnected to the old ZK server, not the new ZK server. 
     53 
     54It seems that ZK client resolves the FQDN to an IP address on start-up, but never again after that. 
     55 
     56=== Missing space in linkgroup === 
     57 
     58RT 9675 
     59 
     60Add additional information in 'ls link group' command to also show used space. 
     61 
     62== PIC == 
     63 
     64Everything is running fine. 
     65 
     66Now have the date for the upgrade to dCache v4.2: 2019-05-28, 3 weeks time.
