[MooseFS-Users] mfs client hang , /var/log/messages: no chunkservers

[九日 <209...@qq...>]

I installed mfs-1.6.27-5 on centos 5.11,it has seven chunkservers ,total disk size is 56T.The mfs filesystem has 72229209 files.
Today ,the mfs client /var/log/messages shows "no chunkservers",and mfs filesystem  hang.
the mfsmaster server /var/log/messages continually print : 
" chunk-server alrerady connected
connection with CS(x.x.x.x) has been closed by peer
",and the mfsmaster OS has a lot of mfs related TCP　connection .


help!
