Can you supply the full log messages below from Apache error log with any prefixes so I can identify what output them.
The mod_wsgi code does emit a message "Python has shutdown", but doesn't emit a message "Connection closed to child with abortive shutdown". So is important that can see the full log messages include any date/time stamp and prefixes. Any other messages around that time would also be useful. If I had to guess, you are using some third party package for Python which assumes that if it has an internal error message that it can force a process shutdown using a signal or call of C level exit() function. Also, although you see the messages "Resource temporarily unavailable" are they transient and after a moment requests start to be processed again? > On 19 Oct 2023, at 10:01 am, Darshan Patil <darshankpa...@gmail.com> wrote: > > Hi, > > I have my apache server where I am using mod_wsgi to run python endpoints > which serve images from the server.
