Analysis on the restart of Apache process Parent:child process exited with status 3221225477--restarting
Phenomenon: Every 1 time (several 10 minutes), the Apache process will automatically restart and leave this record in its error log: Parent:child
You cannot start Apache, or use integration packages such as Wamp to stop the service after the apache service is started, but it is okay to move things to other machines.The problem may be related to the network. I checked a lot of information.
First, find the Apache error report log, and find that there are many debugging errors that are always the same.

. A process in the task_traced state cannot be awakened when it responds to the sigcont signal. The debugged process can be restored to the task_running State only when the debugging process performs operations such as ptrace_cont and ptrace_detach through the ptrace System Call (the operation is specified through the parameters called by the ptrace system), or w
Process state changesAfter the process has been created, the state may change a series of changes until the process exits. While there are several process states, the process state changes in only two directions-from the task_running state to a non-task_running state, or fr

); }The report method that calls iprogressOriginally, it was possible to call the System.Diagnostics.Process.WaitForExit () method to wait for the process to execute, but since this method was called synchronously, it would have caused the UI thread to jam, causing the UI to fail to respond immediately and experience bad. So instead of handling the exited event, this event will be called asynchronous
