HI Tzahi,
             How does( is there any Logic) the kernel selects the processes for killing.
            
             In this  case whrat hapedns to the processes which are sharing resources and processes which are waiting for the resources. if these resources are already locked by another process how does the kernel behaves.

             In a 512MB with 1024MB swap how much space is allocated to kernel and user,
According to previous discussion it is 1GB for kernel and 3 GB for user if we have 4GB of momory.


Thanks,
Venkata jagadeesh.p

I do not completely understand you question, however, if the kernel notices
that there is not enough room in memory or swap, it will start killing
processes until it will have some memory. This is configurable of course.

Please CMIIW.
