Hello- I was just in System update and saw the following error which i have never seen before
I have contacted my server to check this- just wondering if its something that came out with the new core and what it means?
Everything on the site seems to be working fine despite this error so i was curious
Thanks

Its kinda weird...my performance check awhile back was 2600...now its 151 and none of the data for "users online" is showing up?
Otherwise despite these numbers the site is still lightning fast just as it was when it was at 2600

I hadthe same error and contacted my server who fixed it for me. I provided them with a link that Jamroom gave me
http://us2.php.net/manual/en/function.apcu-add.php
I have just installed another site with the same issue and they fixed that for me also.

It's optional, but helpful to get it installed. APCu provides a small, persistent "RAM cache" on the server that Jamroom will use for the locks that it needs when managing multiple processes (mainly around the queue system). I'd recommend getting the APCu support installed if you can - it will help a bit on your site if you get slammed with 25,000 viewers again

My performance check is still down in the 100 range...site is really fast...keeps showing Mysql scores in the 30's
with the site working so fast just seems like it cant be correct- any thoughts on this?

Also- the server just enabled the APCu function...now if you look at the System Check- the actual check is completely missing
Does this only show up in the check if there is an error/

These are just notices - you should NOT see these - make sure you are not running in Developer Mode.

Yeah that is a pretty bad DB score. As long as caching is enabled it will help, but ultimately if it stays that slow your site will be slow.

Thanks brian...I just checked-I am not running in developer mode...the server is working fine as far as speed (performance check has been broke a few weeks) Now i notice other monitoring stuff not working
In the dashboard
1- 5 Minute Load does not work
2-Users online does not work
3- memory Used does not work

The site is extremely fast despite these scores in the 100 range over the last 2 weeks- here is a screenshot from the ACPu cache- everything look ok there?

Also here is a screenshot the day it crashed...see the one on bottom that is around 2200? Well i ran one after that which for some reason is not displaying here- it was 2600+...then a few minutes later i ran it again and i was in the 200's...I think 2600+ tach'ed out the performance monitor and thrashed it

Anyway something happened all at once...but the site continues to run at the same pace as the 2600 test even though most the performance monitor stuff is broke...so its not a critical issue- just the tools are not working- sites running fine

My DB is v 5.6.38
do you happen to have a set of values as a txt file or something that can be submitted to the managed server to optimise this version for jamroom?
I once updated to maria DB and Litespeed...then after an update to one of them it crashed my site and the server could nt resolve it-they are waiting for the next updated version of them to come out so they can reinstall and test..

When i hit 2600 and everything broke my DB score was aunder "3"..now its over 30. even though i am not aware of ANY server changes...thats whats throwing me off...I dont do much on my fully managed server...and they dont do much unless i ask...so its strange

Something has changed on your server - if you're not seeing the load values anymore, then it means that the system() function call is no longer working (or being blocked). I have a feeling a server update might have been performed on your server - I would double check with your hosting provider. Nothing has changed in regards to the load levels in the dashboard in a really long time, so if that just stopped working then something on the server changed.

Thanks for that Brian as i troubleshoot.
I just updated mysql to maria DB 10.1.xx
and upgraded to Litespeed
Moving to maria DB my score went from 30 to 42 ( should be around a 3)
Would this likely indicate my problems are in my PHP settings?
Sorry Im confused and trying to figure out how this works...My thinking was that if i move completely from mysql to mariaDB and that does not fix the prob then maybe its not on the server end?

So:

MariaDB = fork of MySQL
LiteSpeed - fork of Apache

Just changing to MariaDB will buy you a little speed (since it's a bit faster in SOME ways than MySQL). I can't speak about LiteSpeed since we don't use it.

I would not expect just changing to MariaDB to do anything much for speed - sounds like you need to optimize your database config. How much memory do you have on your server? What does your current /etc/mysql/my.cnf file look like?

Yeah - I saw your error log post before you edited it, and it was issues coming from the /store directory, so glad you found that.

So this is where it can get more complex depending on your setup. Since you are only seeing 1 user, it means the IP address for all your visitors is the SAME, which means your web server is not forwarding the IP address of the user over to your PHP install as $_SERVER['REMOTE_ADDR'] - so you need to have your web admin ensure the remote ip address is coming through. If the web server is behind any kind of proxy, then the HTTP_X_FORWARDED_FOR header needs to be set as well.

I saved my PHP configuration using system tools to a html file then zipped it here...thought this might work to show my php settings if interested..

Here are the settings for what you stated..
$_SERVER['REMOTE_ADDR'] 216.198.163.158

I can see in this that $_SERVER['REMOTE_ADDR'] and $_SERVER['SERVER_ADDR'] are different, so that's good - that means YOUR ip address is not coming in as the server address. So I think your online users _should_ be good. Do you still only see 1 online user?

This is good for the size of your server - MySQL should be running really well with this config.
