Error connecting to database

Hi all,

I am facing with the below error while trying to connecting to database

db2 connect to <database_name>
SQL1224N The database manager is not able to accept new requests, has
terminated all requests in progress, or has terminated the specified request
because of an error or a forced interrupt. SQLSTATE=55032

we recently had a physical memory change on the server and the same was reduced.

Regards

Rafi
