search for: freememory

Dear all, I have wrapped a C++ function in an R package. I allocate/deallocate memory using C++ 'new' and 'delete'. In order to allow user interrupts without memory leaks I've moved all the delete statements required after an interrupt to a separate C++ function freeMemory(), which is called using on.exit() just before the .C() call. I am concerned about the following. In square brackets you see R's total virtual memory use (VIRT in `top`): 1) Load library and data [178MB] (if I run gc(), then [122MB]) 2) Just before .C [223MB] 3) Just before freeing memory...

Hello, Thank you for your reply. I am missing an intermediate step as > plot( strptime( Time, format = "%H:%M:%S"), FreeMemory) Error in strptime(Time, format = "%H:%M:%S") : invalid `x' argument > plot( strptime( c(Time), format = "%H:%M:%S"), FreeMemory) Error in strptime(c(Time), format = "%H:%M:%S") : invalid `x' argument does not work. My "Time" data...

...e same time, depending on the workload, can crash the system - I get a kernel trace when this happens. But let's consider a simpler case: one guest with 1.5 Gb RAM, ubuntu 14.03. During the installation the system will again crash. The memory statistics (top or proc/meminfo) will show that the FreeMemory goes down to 12Mb when this happens - which kind of makes sense considering the host will require some RAM to run. But the question is: does libvirt offer any way to prevent this from happening? Some way of not allowing the user to start a guest unless you have enough free memory. I know how much...
