[Planetlab-users] Nodes Wedged?

Wed Aug 1 09:38:36 EDT 2007

Almost a similar situation here. My nodes were being erratic, I removed
them and added 72 new nodes (after checking with CoMon for lightly
loaded, no problems list) - and since the past two and half weeks, I'm
getting "access denied". PL Support said that there's some problem with
the node manager and they have a fix which they are going to deploy
soon. Not sure if that's done or not.

But after seeing your email, I added a new node - and within 10 minutes
I was able to access that. But the same "access denied" for the other
72, which is extremely weird.

Regards
Arijit
