Re: conversion of pdfs in OM 4.9 error - fixed

[Denis Noctor]

Hi there Maxim,

I am torn between whether to write to this reply or a reply you sent me
regarding my last email about conversion. I double checked to make sure I
had ImageMagic / Ghostscript / LibreOfffice and so on install correctly.

I know this probably sounds silly... but the only way I can upload a file
to the Whiteboard is to reboot my server, restart MySQL, Kurento and then
Tomcat... Once I upload a file whether it be doc, pdf, jpg and so on...
the only way I can do an additional upload is to reboot and restart all the
services... if I do a second upload... everything hangs on the "converting
stage"... (Ubuntu 18.04.02).

Any suggestions or recommendations would be appreciated.

All the best.

Denis

Re: conversion of pdfs in OM 4.9 error - fixed

[Maxim Solodovnik]

Hello Denis,

Are you sure you are having 4.9?
If so why do you have Kurento?

Is this issue reproducible on our demo server?

Re: conversion problem during update

[Peter Dähn]

Hi Maxim,

you are right, to add this would help, if it is a common problem.

This is a really old file. It seems that it was already a pdf-file.
Original content of the folder was

HASH.pdf, HASH.swf, library.xml and for each page of the pdf a
_thumb_page-.jpg.

Greetings Peter
