[Kernel-packages] [Bug 2042363] Re: AIX 7.3 NFS client frequently returns an EIO error to an application when reading or writing to a file that has been locked with fcntl() on a Ubuntu 20.04 NFSV4 ser

Per comment#23, the ip from AIX 7.2 client are: 9.20.120.127 name = adia.v6.hursley.ibm.com -- Primary 9.20.121.46 name = amberjack.v6.hursley.ibm.com ? Partner And I searched the trace again with above ips, looks socket cc6f0db2 is created between 9.20.120.127 and nfs server, however

Sorry, I can't distinguish which parts of logs in the attachments (#comment11, #comment12 and #comment13) are belong to the connection from working 7.2 and non-working 7.3. All the attachments have "TCP recvfrom got EAGAIN" which should from the connection for 7.3. $ grep "TCP recvfrom got
