Hi,
We have the same error in the WebIntelligentProcessingServer's trace ( "... 'ping' API. (Error: ERR_WIS_30270)" ) after starting Platform BI 4.1 SP4 Patch 14 (OS:linux) but the service continue to work.
After 2 hours, all connections are reserved and we have another error on the scheduling job ;
The maximum connection limit has been reached. (Error: RWI 0000).
