Thanks for the input! Ill try setting up some swap - could have really thought of that one
I tried to get some error-msg from Eclipse though the error came from the JVM itself (dialog popped up):
"JVM terminated. Exit code=-1 /usr/bin/java -cp /mnt/sdc2/java/eclipse/./startup.jar org.eclipse.core.launcher.Main -os linux -ws gtk -arch x86 -showsplash [...] -showsplash 600"
At that time, eclipse was still "running" in the console.
Once you closed it, eclipse was gone too without any message.
I let free check mem every 3 seconds, this is the worst output it gave me - that was shortly before JVM hang up.
Code:
             total       used       free     shared    buffers     cached
Mem:           250        248          2          0          5         45
-/+ buffers/cache:        197         53
Swap:            0          0          0
Ill just try with some swap now...
