login via dbmcli hangs - database is down - no restart possible

After a system restart it is not possible to log into one of the two databases on the server to restart it.

Trying to log in via dbmcli never returns.

The dbmcli process takes 100% cpu

100 0.1 7:22.77 dbmcli

After using ctrl-C we get:

Error! Connection failed to node (local) for database <dbname>:

Reading header from pipe:(32:Broken pipe

We have a second database on the same server - there are no problems.

Nothing is written to knldiag or any other of the log files there.

MaxDB version is 7.6.06.03

What can we do ?

Regards

Bernhard

    Hello ,

    our database is now down for 1 day, because we cannot start it.

    Has no one an idea how to log into an instance if dbmcli hangs completely ?

    Is there any way to find out the reason for this?

    Is there a tool that you can use to do a backup of the database - wihout connecting via dbmcli?

    Any help is appreciated, thanks in advance!

      Just to close this case:

      We solved it by creating a new instance with exactly the same geometry as the old one

      (same number and size of database- and log-files),

      stopped it and coppied the database files from the non-working db to the new one.

      Restart was successfull and everything works fine since then.
