    hello, I originally posted this in the community forum but got no response…

    My website was not accessible the other day and when I asked my webhosting company, their response was:

    It appears the site was suffering from 0% CPU usage apache processes.  Are you pulling any external API’s or content? Did you recently do anything within the EE backend.  The 0% CPU usage apache processes are filling up again:

    PID USER   PR NI VIRT RES SHR S %CPU %MEM   TIME+  COMMAND                                              
    6181 ehxxxx   20   0 244m 16m 3356 S   0 0.1   0:00.14 apache2                                                    
    6182 ehxxxx   20   0 244m 17m 3500 S   0 0.1   0:00.28 apache2                                                    
    6183 ehxxxx   20   0 243m 16m 3524 S   0 0.1   0:00.58 apache2                                                    
    6343 ehxxxx   20   0 244m 17m 3512 S   0 0.1   0:00.44 apache2                                                    
    6539 ehxxxx   20   0 235m 7132 1192 S   0 0.1   0:00.01 apache2

    I can’t say exactly what caused the 0% CPU usage apache processes other than they’re usually caused by apache waiting for something to happen thats taking awhile.

    The webhosting company cleared the processes and my site is up again but I’m confused as to what any of this means. this site is EE v2.5.0 with no out of the ordinary add-ons (wygwam, matrix, cloner, switchee, image sizer).

    I’m just wondering if you could offer some insight in case I am doing something wrong.

    thanks!

    Hey there peachorama,

    Thank you for posting your question.

    If you are using a basic install then I do not know why it would be doing this.

    Your hosting provider should be able to tell you a little more about what is going on. They have tools on their end to do a little more digging, find out what’s really going on with a few commands. All the scenarios I can think of, a server admin would catch pretty quickly, so I am guessing those are not in play here.

    Is this Engine Hosting? I notice the user is ehXXXX? They had an outage earlier this week. I believe it was Monday the 5th. Yes, they have a status page here. Monday they had issues and looks like some today. Could be it carried over through the week for some. Might be related to your issue.

    Wish I could be of more help.

    Is there anything else I can help with?

    Cheers,

    hi shane, yes, this is enginehosting. they did not seem think this issue was related to the outage but i find that hard to believe when all was running normally before they started experiencing problems.

    another strange thing that is happening with this particular website is that after the EH outage, my output profiler and template debugging results were no longer displaying - both in the system and front-end pages. do you also think this is a hosting issue or something else? i’ve asked EH about this but they are currently busy dealing with the outage right now.

    thanks, i really appreciate your response and expertise!

    Hey there peachorama,

    I would wait until things settle down and check back with EH. See if they can troubleshoot the issue.

    I cannot think of a reason that that debugging would stop working on the backend like that. Very odd.

    Cheers,
