After upgrading from IC 4.x to IC 4.5 or IC 4.5 CR1 some customers have got problems with search operations:
f.i. status updates are not shown up, search does not work any more (after a while).
Found following error messages in systemout.log:
FreePool E J2CA0045E: Die Verbindung ist beim Aufruf der Methode createOrWaitForConnection für Ressource jdbc/search nicht verfügbar.
I increased the connection pool size of datasource jdbc/search from 10 to 20.
It seems to solve the problem. But I am wondering, why I can't find a hint form IBM and google out there..
Somebody out there who ran into the same situation??
