BasicResourcePool: An idle resource is broken and will be purged.

User_3Z4KKMay 4 2022

I installed Endeca on Ubuntu according to official document. Everything is well until run baseline_update.sh.
I checked the log in /opt/endeca/apps/MyApp/logs/forges/Forge and it is empty.
And then I checked /opt/endeca/PlatformServices/workspace/logs/main.1.log, there is a exception as follows :
WARNING: 04-29-2022 17:41:32.842 BasicResourcePool: An idle resource is broken and will be purged.
Caused by:

I searched the related topic but didn't find the specific solution. Has anyone ever had this problem and know the solution? Deeply grateful!
