I have been having random freezes with Minecraft Forge. I have also been using Optifine but it still happens without Optifine as well. What the issue is, is that Minecraft will randomly freeze, from 10 seconds to 10 minutes. When I look in the console nothing happens at all, it's perfectly normal.
This issue has been happening since 1.2.5, happened in 1.3.2, 1.4.6/1.4.7, and now 1.5.1 and 1.5.2. I know it isn't my computer cause my friends have the same issues as well.
Any ideas as to why this happens?
