Is the issue rising in both development and production?
Is it related to some specific PDF?
If last one, may you provide your file?

Yes on both, dev and prod

It happens only sometime, sometimes it works sometimes got crash

It seems there's something weird on your webserver.
May you try "www.radaeepdf.com/documentation/fdb70bf8436abd82bec0.pdf";
It's your file from one of our own webserver.
We've just checked it on Android 8 and Android 7 without issue.

Have you checked this www.radaeepdf.com/support/knowledge-base?view=kb&kbartid=18 ?

with your provided url it looks great.
we are going to add this information to our web server, will try and give you feedback.

the last changes solved my problem.
Thanks
