@wyang007 Yes - the jobs read from the xcache. Looking at the configuration I see the following in the xrootd config on the worker node ``` pfc.ram 7g pfc.diskusage 0.89 0.90 purgecoldfiles 2d 5 pfc.blocksize 16m ``` Actually we have two configuration files - for the gateway and the proxy. Would it make sense to post both of them here for you to have a look? @xrootd-dev and @wyang007 Both of you mentioned CEPH being overwhelmed. Is there anything else (other than the "Operation expired" error) that xrootd would expect that I can see on the storage side? From what I understand the storage admins at RAL see that CEPH is healthy from the point of view of the storage. Thanks and Cheers, Raja. -- You are receiving this because you were mentioned.
