Hi soren, Thanks for useful information on this. We are not spawning children from the pre/post config, but still i could see the long lost child alerts. This alerts is coming only on graceful restart(SIGUSR) of the server and not on restart on the server. When i did debug on the worker server_main function i could see that after the run config is done for all the modules, there are many process ID thrown with "long lost child", and after that the server resumes with the children. Iam wondering is the alerts are showing because of the custom modules what we are using a longer time to finish with?. Please throw some light on this. Thanks in advance.
