In case the EVENT_WR-H-ICAP-501 warning (Possible ICAP problem - response time repeatedly too high) appears frequently, this can have the following causes:
- A network problem in the back-end network.
- An overall bad performance of the ICAP server.
- A misconfiguration of Airlock Gateway.
This event is generated if 3 ICAP requests within 1 minute take more than 2 seconds each.
Since the bad response time affects the overall system performance, it should be fixed soon. Each pending request consumes resources on the Airlock Gateway. The total time each request takes is almost as important for the performance as the total number of requests per second.
In this case, we do not recommend event adjustment, which could only suppress the symptoms instead of addressing the causes.
