We are using Lync Server 2013 Enterprise with Office Web Apps 2013 Server farm deployed. Latest updates installed.
I’m getting issue with sharing PowerPoint presentations. Small files work just fine.
When I tried to share large .pptx file about 10MB I got error message:
“Either you've lost network connectivity or our server is too busy to handle your request. Please check your network connection and try again later”
MS support recommendation was to increase value of WAC farm MaxMemoryCacheSizeInMB setting.
Changing MaxMemoryCacheSizeInMB from 75 to 512 fixed this problem.
Now I get the same error with files over 20MB. MaxMemoryCacheSizeInMB is set to 4096, but I still get the error notification. Presentation files contain png and bmp images with resolution from 900px to 2400px.
Has anyone ever faced this problem? Maybe it’s some kind of limitation on file size or WAC server upload timeout, images render..
Thanks.
