Error 2341 after ndbd restart from nodes (no replies)

Hi guys

After shutdown command on the management console as seen below:

root@lb1:~# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> shutdown

And when restart the nodes with ndbd, i got the following message:

Status: Temporary error, restart node
Message: Internal program error (failed ndbrequire) (Internal error, programming error or
missing error message, please report a bug)
Error: 2341
Error data: dbdict/Dbdict.cpp

Could someone help me out with this?
