Ubuntu 9.04 has now been reinstalled with ext3 instead of ext4. So far this problem has not occurred with ext3 and it therefore seems likely that the bug was related to ext4.
** Description changed: - I am running a clean install of Ubuntu Jaunty 9.04 and has since its release been experiencing sudden excessive hard disk load as well as sudden memory leakage. This results in a lock-up of the system because of probably either usage of all ram memory and swap or because of severe hard disk load. When this happens, the system becomes so slow that it is very hard to examine it further. + I am running a clean install of Ubuntu Jaunty 9.04 with ext4 and has since its release been experiencing sudden excessive hard disk load as well as sudden memory leakage. This results in a lock-up of the system because of probably either usage of all ram memory and swap or because of severe hard disk load. When this happens, the system becomes so slow that it is very hard to examine it further. I have not been able to notice any clue to the problem in the system logs, however I might have overlooked something. The problem might have something to do with hard disk intensive applications, since this has happend when I have used: VirtualBox to import a saved WM from a external harddrive, and start the new WM. This time it used up 2GB of ram as well as almost 3GB of swap. However by killing the Virtualbox in time I managed to recover the session. Vuze/Azureus to download torrents. This slows the system down, but does not immediately leak memory. But suddenly hard disk load spikes and the system is almost not responding and therefore it is not possible to recover the session. If I wait to see if the problem resolves itself, the system eventually locks up completely. GIMP to do intensive image editing. This is similar to the case with Vuze/Azureus as it is not possible to recover the session. More recently this happens about one or twice a day while not using any hard disk intensive applications, but more at random. For example while programming in Netbeans, surfing with Firefox or reading Pdfs in Evince. In all cases it is possible to safetly reboot the system with Ctrl + Alt + Sys rq and R + E + I + S + U + B Trackerd is not installed on my system and therefore should not be the source of the problem. I have tried to use both the latest generic kernel (2.6.28-13-generic) and with the proposed one (2.6.28-14-generic) without any difference. A full memtest86+ has been completed successfully. The system did not have this problem with Ubuntu 8.10.
