Pls help me.

Have u checked if the adapter connection is working fine during this time.

Yes, it’s working at that time.After I reinstall WmRoot,wmPublic packages, notification is work not stable.Is this affect on it ?

What do you mean by reinstall WmRoot, WmPublic?

Did you copy the packages from another server? Does your server have patches/fixes that change files/classes in these packages?

I copied from backup files from current server.Because these package is partial so I have to do that.

Is it possible to retart the server.If so restart it and see whether you are geeting those errors again or not.

I restarted it, but it still happen.

Check for the connections,if they are ok…then I guess u need to disable the notification and delete the tables related to it(trigger table etc).enable it again and see if it works.
