Prev: db2 activate database results in 1226 - Overflow agent is not allowed
Next: Unicode database

It seems that maxagents or something similar has been reached. To narrow down
the problem, I would need the output of:

db2 get dbm cfg
db2 get db cfg for <dbname>
db2 list applications

Please run those commands as db2inst1 and post them here.
