This is a shout out to any Moodle server admins out that could help us with their experience of configuring and working with the VLE.
We face this serious issue at our institution with Moodle every now and then where both the servers ( load-balanced) gets used to their maximum capacity and then fall over. The only way to bring it back to life is to restart it and things go normal after that.
To be a bit technical with the issue we are facing, below is the response from our Corporate Apps and Database Manager :
Same old problem of both web servers locking up in the W state, i.e. sending reply, with all workers being used. The servers get really wound up to a huge load, and just stay there
Doesn't matter whether we have one or two servers, all that happens is that you end up with 400 or 800 stuck workers
Anyone out there facing a similar issue where the Apache workers get stuck after a certain point which clogs up the server.
Feel free to ask me any specifications about the server and I'll try my best to be accurate.
Many thanks in advance,
