We have a web based application running on our Citrix environment. We are running Windows Server 2016 (1607) and Citrix VAD 1912 LTSR CU1. The users login to the web based application and eventually it will trigger the opening of a PDF within Internet Explorer. This process will work most the time but we find after the user does anywhere from 7-10 instances of the process Internet Explorer will crash.

We first monitored performance on our server but identified there are no CPU/RAM bottlenecks. We even isolated users to one server to test and they still have the issue. We recently enable Crash Dumps for Internet Explorer so we can further determine the issue. I've reviewed the crash dump along with Microsoft and we've found the crash is due to AcroRd32.dll. We were running an older verison of Adobe Reader so I've updated to 2020.012.20041 and we have the same issue. Is there anyone on the Adobe side who can review the Crash Dump I have to provide insight as to what could be causing it? We've tried with Protected mode disabled and the issue continues.

Thank you!
