We have been getting many cases where model sharing read in is hanging randomly. The progress bar just jams and looks like nothing is happening. Sometimes it helps to restart Tekla Structures and try again, or try with a smaller number of packets. It looks like there is nothing wrong in the packets themselves as the problem is random, it is just the read-in process which is jamming.
We have been investigating this issue and it seemed to be related to Azure Blob Storage service. The network communication to Storage Service is occasionally hanging during the download. This seems to happen more likely with large baselines or packets with hundreds of Megabytes data sizes.
We have found a workaround with a special back-off setting when communicating with Azure Storage service and added this workaround to the new Cache Server version. In case you are facing this issue installing the new Cache Server is the quickest way to get this workaround into use.
The Cache Server is anyway recommended to be used in most cases. In case there is a server in an office and a VPN connection then the Cache Server can be shared with many users in the same area. If not then the Cache Server can be installed in the user's workstation as it's really lightweight.
The fix for this issue is included in the following Tekla Structures Service Pack installations (does not require Cache Server):
- 2020 SP3
- 2019i SP7
- 2019 SP8
- 2018i SP9
