Popen Error Cannot Allocate Memory


I am seen in darkness and in light, What am I? Part of that is a call to subprocess.Popen to get the output of ps. My day job keeps me busy into the evenings and so I thought I'd simply drop a courtesy note to you here to let you know I haven't disappeared.

Accepting you answer :) –MAG Aug 7 '14 at 18:29 I know that popen will return the mem allocation failed error if you've hit the system limit on open Using these tools will answer that for you. This is something. I would be very interested in seeing what the above commands display for your process when it has just finished launching and running for the first time and after 24 hours http://stackoverflow.com/questions/31033705/why-is-popen-failing-with-cannot-allocate-memory

Python Cannot Allocate Memory

Is that what you're saying? Why do languages require parenthesis around expressions when used with "if" and "while"? The files are only 200-300MB. This is called by doChecks() starting at line 520.

I would expect to see more useful input from logging memory conditions on every spawn and seeing how failed calls and successful calls correlate with the state of memory, swap etc. Or will a client/server/socket solution be needed? the code paths through the Linux kernel when it has even a tiny bit of swap available have been exercised far more extensively than those (exception handling paths) in which there Python Memory Leaks The formula for virtual memory is usually like: SwapSize + 50% * PhysicalMemorySize.

Python Cannot Allocate Memory Update You can check rlimits from with your python script using the resource module: import resource print resource.getrlimit(resource.RLIMIT_DATA) # => (soft_lim, hard_lim) print resource.getrlimit(resource.RLIMIT_AS) If these return "unlimited" -- (-1, -1) Python Multiprocessing Cannot Allocate Memory Since glibc 2.9, this argument can additionally include the letter 'e', which causes the close-on-exec flag (FD_CLOEXEC) to be set on the underlying file descriptor; see the description of the O_CLOEXEC

however, it doesn't say if EAGAIN is to be returned by other RLIMIT* violations. check over here Here are the applets I have running: The applets are Indicator Applet 12.10.1, System Monitor 3.5.92, and a "notification Area". According to the man pages for fork()/clone() the fork() system call should return EAGAIN if your call would cause a resource limit violation (RLIMIT_NPROC) ... The application sounds like it's overrunning the system with subprocesses. –S.Lott Aug 1 '09 at 17:31 1 @S. Oserror: [errno 12] Cannot Allocate Memory Odoo
