1 Run Nginx separately, it works fine: image image

2 Run DTO with Nginx, 2.1 Configure DTO: ➜ DTO git:(main) ✗ accel-config disable-device dsa0 accel-config disable-device dsa2 accel-config disable-device dsa4 accel-config disable-device dsa6

accel-config load-config -c ./dto-4-dsa.conf

2.2 Run DTO with Nginx: image

3 Expect: when Nginx keep running, dto need keep running too.

Hi, DTO logs the above output when the process terminates. There must have been one nginx process that terminated and thats why DTO printed above logs. I reproduced the issue on my system and I can see that the process (pid) no longer exists for which DTO printed above logs. There are other nginx processes that continue to keep running. I think it is an expected behavior. Please let me know if you think otherwise.
