Hi, maintainers: I just rebooted the problematic NFS server, but the problem soon appeared again! In other words, some NFS clients are hanging and server is filled with the error message:
# dmesg | tail -2 [ 6180.718237] RPC request reserved 84 but used 272 [ 6180.732857] RPC request reserved 84 but used 272 # dmesg | grep RPC | wc -l 2519 # uname -a Linux home 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1 (2018-04-29) x86_64 GNU/Linux Please help!
