I need to download all files from a community. It's about 5.23GB. However, using the normal download as a zip file, I can only download a maximum of 4GB.
This seems to be a hardcoded setting in Files.ear. I couldn't find a config option.
If you check AppSrv01/installedApps/ConnectionsCell/Files.ear/config/com.ibm.lconn.share.platform.bootstrap.properties there is a config line:
# Maximum size limit for zip download. download.zip[@maximumSizeInMb]=4096
I switched this to 100 in my test environment and got the error with 100MB instead of 4GB now. I have no clue if this affects the performance or memory consumption if you increase the value, but the 4GB is set in this bootstrap file with download.zip[...].
I tried to change this setting on one cluster node and have then been able to download the file. While downloading, I saw an increase on CPU usage of nearly 100% on one core, but no increased memory consumption. After downloading I switched back to the original 4096MB.
