ssh_exchange_identification: Connection closed by remote host

[valshare]

Hello,

today i want login into one of our OpenVZ Container. SSH login failed. The i want to login into our PVE Server, but login failed, too with the error message:

ssh_exchange_identification: Connection closed by remote host

After login failed with ssh, i try to login via http on the server. The Master Server shows: no sync.

In the PVE in Log:

I dont want to restart the PVE with all the OpenVZ Containers only if this is the only wait.

Migrating to one of the other machines failed too.

Anyone can help?

Do you have resource shortage (ram)? 'Cannot allocate memory'

Hi,

there are 16 GB of RAM in the PVE with 8 Machines. 7 Machines with 512 MB RAM assigned and one machine with 2 GB assigned.

But i think now there is a other problem. Have shut down all machines remotely and wanted to reboot the server. Server didn´t fired up. Now i must start my reserve machine manuell and mount the iscsi-storage on this machine. Hope it works. ;-)

Can look tomorrow, what happend to the PVE Server.

Hi,

today i have looked for the error. It was a memory hardware defect.

Thanx and a good day....
