Hi Anders, A few questions: 1) Do you have similar issue without ssl support? 2) Do you use SCOOP or Thread concurrency mode? Do you have same issue with any mode? 3) You said, it is about 10 times. Can you tell us the period? 10 times a day, a week, .. since your server is deployed? 4) When this occurs, do you know if the server was running for a long time? or this does not matter? From the log, we have the pseudo id of the incoming request #.# , and it seems the first error appears quickly. 5) Do you know when the 100% CPU issue happened? To solve it, did you had to restart the server? 6) Do you have by any luck, a system that I can run to reproduce the issue and debug it ?
