Version: unspecified (using KDE 4.7.3) OS: Linux Whenever I run a Java application (Eclipse, Oracle SQL Developer) under KDE, the system becomes unresponsive for some time (up to several minutes) while system load increases considerably until eventually the Kernel's OOM killer kills the Java process. This never happens under XFCE4. Reproducible: Always Steps to Reproduce: In a KDE session, run eclipse or SQL Developer. Actual Results: System is unusable for some time, until Java application gets killed by OOM killer. Expected Results: Well, a running Java application in a usable desktop. OS: Linux (x86_64) release 3.0.0-14-generic Compiler: gcc
Eclipse is very resource intensive, if your computer does not have enough RAM memory it is going to trash like you described. How much memory does it have? If there is no memory leak in a KDE program I do not see what we can do about this problem.
I couldn't reproduce this bug or find duplicates.

So, any news about this problem? Should we blame OpenAFS for it?
(In reply to comment #4) > So, any news about this problem? Should we blame OpenAFS for it? Oh, sorry, forgot to write a followup. After switching OpenAFS from memcache to a disk-based cache, the problems went away. However, I still think that even the remaining 2GiB in the memcache case should be more than enough RAM for a desktop system.

That is what everybody wanted. My Linux in runlevel 1 takes about 290 MB. Runlevel 1 means no Xorg, no KDE desktop, nothing running, but the kernel and the command shell. With the login window (kdm) running it takes about 740 MB. After logging in and launching eclipse it takes a little more than 1 GB. Launching kmail it takes about 1.01 GB (kmail seems not to take that much ram memory). After launching chromium with four tabs the memory usage sky rocket to almost 1.9 GB of RAM. Dependending on the program set you use 2 GB is not enough. I must say that I am a little disappointed with the ram usage in this new notebook with Intel Core i7. I also own an old notebook with a Turin64 processor and in that old notebook the ram usage is much better than this one with the same set of programs running. The difference is about 300 MB of ram, which is more than one third of program set's ram memory when running on the notebook with Core i7. I use Gentoo optimized for each processor, maybe the optmizations for Intel processor causes this effect, I do not know.
