Randomly unable to download large files from Windchill PDMLink
Modified: 29-Mar-2024
Applies To
- Windchill PDMLink 11.1 to 12.1
- PTC Cloud Installations deployed using the Amazon CLB (deployed Spring/Summer 2023 or earlier)
Description
- Unable to download larger sized files (typically larger than 350MB)
- Unable to download the files larger than 600MB
- Content download of large files randomly fails
- During content downloads, the Amazon Classic Load Balancer (CLB) may reset network connections with the Windchill server
- Apache access log shows only part of large files being downloaded (usually around 350-600MB) and the file being requested again but failing with a 500 response:
