We recently installed EPDM v10 with Administration v10.5. We have three vaults and six remote archive servers connected via VPN tunnels..
We're having a problem with one of vaults whereby users are unable to log in and connect to the vault randomly with the error "Could not connect to the archive server "xxxx" for the vault "yyyy". The only way I've been able to fix this is by logging into the vault Administration console with the admin user and doing nothing else. Somehow logging into the server "wakes up" the vault and the remote users are able to connect successfully with no errors. The problem only occurs once a day, but there have been several days where we haven't had the issue.
When this problem happens we've confirmed the VPN tunnel is up by pinging the vault server successfully. The replication tests always come back successful as well.
The other two vaults and associated archives do not have this problem.
