Weird memory usage pattern with Java 1.4.2_01 on some configurations (memory load climbs up and drops back repeatedly). Use latest version of JRE. JVM issue: Azureus under linux, writing to FAT partitions: Incremental File Creation needs to be turned on. IRC bar doesn't scroll correctly. If Azureus crashes when double-clicking on IPs or when trying to display the "About Health" window, please reinstall Azureus using the complete installation file (the auto-update didn't update SWT, which is used to display those windows). Importing downloads from another client: From python clients 3.3 onward, you need to make your client either pre-allocate the space used by the files or try and finish the allocation manually. If it can't be fully allocated, then it's not safe at this time to resume the in-progress download with Azureus.
