[PROBLEM] System freezes after a while

[TheOldPresbyope]

does this error in /var/log/samba/log.wb-MOODE has to do with the issue?
(it is repeated periodically)

Code:

../../source3/rpc_server/rpc_ncacn_np.c:454(rpcint_dispatch)
 rpcint_dispatch: DCE/RPC fault in call lsarpc:32 - DCERPC_NCA_S_OP_RNG_ERROR

No.

It has to do with the winbindd process, which IIRC is being started because we run a samba server in moOde. You'll find the error message has been posted on many different forums over time. While annoying, it seems to be harmless.
