Since a couple of weeks, all images of my dokuwiki are loading in a unstable. When loading a page with 3-4 or more images, anyone of them brings a 500 internal error; and every reload (F5) brings a different image broken (for example: in first F5, image 001.jpg is broken with 500 error; in second F5, 001.jpg loads OK but 005.jpg shows a 500 error; in third F5, 004.jpg shows error and other shows right; in some F5 all images renders correctly, etc.)
I'm using popupviewer plugin, but even when it's disable, the error 500 is showing.
It
loos like that internal resize is working in every page load, what is causing server load - but I'm shot sure about this.
In cPanel, error log shows something like this:
[Sun Nov 13 21:21:29 2016] [error] [client 186.XXXX] (12)Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp for /home/carlosna/public_html/orgaopedia.com.br/doku.php, referer: http://orgaopedia.com.br/instrumentos/estatisticas
[Sun Nov 13 21:17:15 2016] [error] [client 186.XXXX] (12)Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp for /home/carlosna/public_html/orgaopedia.com.br/doku.php, referer: http://orgaopedia.com.br/instrumentos/basilica-nossa-senhora-carmo-campinas
This dokuwiki is installed in
http://orgaopedia.com.br/
All pages with at least 3 or 4 images are rendering with some 500 error; some
examples are:
-
http://orgaopedia.com.br/instrumentos/basilica-nossa-senhora-carmo-campinas (7 images)
-
http://orgaopedia.com.br/instrumentos/seminario-santo-antonio-agudos (10 images)
-
http://orgaopedia.com.br/instrumentos/igreja-senhor-bom-jesus-bras-sp (19 images)
Any idea what I can do to fix this?
If the resize is really the problem, is any way to force internal core to use only cached/pre-resized images? I've played a lot with configurations (including cache options), but without success.
Thanks.
