I am trhowing off by the date 7/8/11 here, unless you changed it. 

Restarting the entire cell, dmgr, nodeagents and all JVMs seem to work for me in cases like these. 

Thanks for your advice,are you sure that this gonna work because we do restart activity every weekend.

Because of this error.

Jason, that is the solution that is worked for me. Usually it is port conflicts in errors like these, are all your JVMs coming up clean ?when you restart every weekend is it just WAS or the entire host .  

Yes buddy, We are restarting entire environment including JVMs. But i didn't see any error like port confliction. 

Hi Jason,

  Review all nodes time (DMGR NODE and NODES), they need to be synchronized.

  Have you all your ports fixed or some of then are *?

  if the problem is with a firewall, the ports should be in state SYN_SENT.
