Overloading host when uploading galleries

  • When uploading multiple images to the nextgen galleries, it seems I am overloading the server from my hosting provider (shared hosting ~1500 web sites hosted on a single 8 core server). He once set my site on suspended when I was uploading images.

    I know overloading has been an issue in the past, but I can not find anything about it in the changelogs of the last versions.

    What can I do about this?
    The published images height or width will never need to be larger than 640 pixels. Can I set this to prevent overload?

    I’m able to edit php scripts, only need to know where i’d best change it.

    Other ideas also very welcome.

    Regards,
    Jack

    @jack All – It seems you have identified the root cause of your issues with a web host serving 1500 sites from a single server … as it is, what are the server settings you see under Gallery > Overview? We can start there …

    @jack All – Those settings appear fine and should be able to handle image uploads without any issues in most cases. How many images are you trying to upload at once? What size are the images that are being uploaded? If you are uploading the full size image (as produced by a DSLR for example) and automatically resizing to the 640px limit you might consider resizing them before uploading instead.

    Are you seeing any error messages during upload or in your server’s error_log files?

    The galleries contain about 75 pictures per article, size about 80~100k, pixelsize max 800 height or width.
    The ngg automatically resize option is switched off.

    There are errors in the log. Multiple lines show the following error for every uploaded image, occurring every 2~5 seconds:
    [Fri Sep 05 09:34:21 2014] [error] [client x.x.x.x] Attempted to upload image/jpeg., referer: https://www.mydomain.be/wp-admin/admin.php?page=ngg_addgallery
    The hosting provider states that their logs show lines proving the overload:

    Srv	PID	Acc	M	CPU	SS	Req	Conn	Child	Slot	Client	VHost	Request
3-161	24741	12/26/22698	W	11.13	5	0	233.2	0.72	361.37	84.198.215.77	www.mydomain.be	GET /nextgen-image/2539/120x90x100/crop/5f98c65771988c6c706dfc6

    etc…

    They refuse to help me any further with this issue.

    I’m sure it is not a client side issue. The homepage shows about 12 thumbnails in the random gallery widget and no other galleries are present on the hompage.
    Site runs WP3.9.2 with X-theme and W3TotalCache.

    @jack All – Thanks for those details but they really are not pointing to anything that seems directly related to NextGEN Gallery.

    Do you still have this issue if you switch to a default WordPress Twenty series theme, clear all of your caches, deactivate W3 Total Cache, remove all if its artifacts (there are generally several) and try again?

    It is possible (although unlikely) there is something in the theme (extremely rare) or a W3 Total Cache setting (first thought) that may be creating this issue …

    … I also find it troubling that your web host “refuse to help me any further with this issue.”
