Hi, we already successfully deployed packages with size of 15 GB with multiple files with 9.6 SP2. It is not nice and it takes time to load, but it works.
What exactly is the error message? Do you see parts of the package beeing downloaded to sdmcache of the client? Since you mentioned timeout, did you set "enable package installation timeout" under the package configuration?
The install of this app is BATCH based, so I select BAT Application and add the additional files either UNC or HTTP. Takes about 10 minutes to process all the files before it will allows me to save the Package. When I hit save it takes about 15 minutes before the application is saved. if I deploy it via PUSH / Accelerated to a system on the same subnet it gets about 300meg and just stops transferring files. No Errors during the process. When the job finally stops it states error downloading files. I have moved the job timeout to 240 minutes but it stops way before that.
I have been successful creating a Provisioning Template then creating a Provisioning Package. That seems to deploy all 12GB in about 20 minutes then starts the installation. Only negative there is that it wont work through the CSA.
hmmm, what about trying to use selfextracting zip executable to pack the files in lets say 500MB parts...Maybe it not the size of the package more the count of small files.
