Hi All!
The bigger pages presentation upload was interrupted in some cases randomly.
I checking the created png files seems not done to export all pages on
PDF2PNG conversion.
The cause of the problem:
Imagemagick has reached its processing limits.
~serv:/opt/open510/logs# convert -list resource Resource limits: Width:
16KP Height: 16KP List length: 18.446744EP Area: 128MP Memory: 256MiB
Map: 512MiB Disk: 1GiB File: 768 Thread: 4 Throttle: 0 Time: unlimited
To solve this problem, you need to raise the memory limits:
nano /etc/ImageMagick-6/policy.xml
Need modify (and check memory consurption on conversion runtime eg.: low
memory and swapping):
...........
<policy domain="resource" name="memory" value="1GiB"/> <-Increase this
<policy domain="resource" name="map" value="2GiB"/> <-Increase this
<policy domain="resource" name="width" value="16KP"/> <policy
domain="resource" name="height" value="16KP"/> <!-- <policy
domain="resource" name="list-length" value="128"/> --> <policy
domain="resource" name="area" value="128MB"/> <policy domain="resource"
name="disk" value="4GiB"/> <-Increase this
...........
convert -list resource Resource limits: Width: 16KP Height: 16KP List
length: 18.446744EP Area: 128MP Memory: 1GiB Map: 2GiB Disk: 4GiB File:
768 Thread: 4 Throttle: 0 Time: unlimited
And working fine!
Alvaro please add to this tricks help to install guide.
