Apologies Maxim for the late reply, I increased the amount of RAM on my AWS instance and this has addressed the problem. I am a little bit surprised how much RAM is used for the conversion processes though.
I was, however, able to replicate the upload conversion problem.... but under extreme circumstances on the *https://om.alteametasoft.com:8443/next <https://om.alteametasoft.com:8443/next>* platform - I accidentally tried to upload a PDF file (a small file - about 1.5 megs... but it has a LOT of pages, over 600!!!!!!... mainly text) - I know, I know and I'm sorry :) I should have checked it first before uploading as the chances of anyone doing this are zero... but it led me to think.... When I previously tried to upload documents (with low RAM), everything seemed to "hang" on continuously converting... with no error message (presumably as everything is being dealt with separately by ImageMajick)... and nothing can be seen except by digging into the logs. The only way to stop the process was to cancel and exit the room... sometimes resulting in an "internal error". Would it be possible to add something such as setting additional limitations" (for example on the admin/configuration page) similar as to limiting file size upload, PDF conversion quality and so on..... but restricting how many pages are to be converted when uploading a doc, ppt and pdf file ? For example, if a user uploads a document of more than 10 pages to be converted.... that they are prompted with a message to say that documents of "x" pages or less can be only converted - please try again" - I think this would be extremely beneficial to the non-suspecting user who tries to upload a file with too many pages and does not know what is happening as a result --- of worse - crashes the platform. Hope this is of some use. All the best, Denis.
