Looking at the Apache error log on my server this notice appears frequently each day
mod_python: Creating 4 session mutexes based on 50 max processes and 0 max threads.
Today for example, it has occurred 7 times already between 23:59 and 09:35. Yesterday it was 15 for the whole day.
Apparently mutexes are used in mod_python for session locking, so I understand this will limit the PHP requests to 4 per user. My website uses Ajax calls once per minute to update information so I understand this could be maxing out the sessions provided by server.
But my question is, why does this notice appear so frequently? Is it happening for each access by a unique IP per day, or is it a problem with the server trying to continually reconfigure itself?
