stab in the dark you're suffering from socket issues.
1) how are you setting chunks, package customiser or just standard max chunks via the settings menu? We haven't changed anything here. Please note that some plugins can reset chunk settings when chunking issues occur, but this can be triggered on socket issues, though rapidgator doesn't have such code, uploaded does. Once nochunk value is set, you will have to manually reset in order to be able to download with higher value again. No chunk code has been present for years,
2) I don't believe we would have introduced those issues. Connections/Sockets are provided via Java API and that hasn't changed at all.
3) probably attributed by the over all issue you're suffering from. What antivirus software, what firewall software? Please provide logs so we can analyse.
