Created attachment 1517534 [details] NFS4 blocked processes Had a full system deadlock on what looks like NFS4 on kernel-4.19.10-300.fc29.x86_64. Find attached the stacktraces of all of the blocked processes. This has happened a number of times over the last few days.
Probably related, but near the same time, on the EL7.5 server running 3.10.0-862.14.4.el7.x86_64 I got a rash of these: 15:06:23 kernel RPC request reserved 84 but used 268 15:06:23 kernel RPC request reserved 84 but used 268 15:06:24 kernel RPC request reserved 84 but used 268 15:06:27 kernel RPC request reserved 84 but used 268 15:06:30 kernel RPC request reserved 84 but used 268 15:06:33 kernel RPC request reserved 84 but used 268 15:06:36 kernel RPC request reserved 84 but used 268 15:06:36 kernel RPC request reserved 84 but used 268 15:06:40 kernel RPC request reserved 84 but used 268 15:06:43 kernel RPC request reserved 84 but used 268 15:06:46 kernel RPC request reserved 84 but used 268 15:06:46 kernel RPC request reserved 84 but used 268 15:06:46 kernel RPC request reserved 84 but used 268 15:06:46 kernel RPC request reserved 84 but used 268 15:06:46 kernel RPC request reserved 84 but used 268
