php - Java on CentOS : not enough memory -


when make command in php like:

exec('java -version > test.txt');

the file test.txt created error inside :

there insufficient memory java runtime environment continue.

native memory allocation (mmap) failed map 2555904 bytes committing reserved memory.

an error report file more information saved as: /tmp/hs_err_pid25505.log

the error report file does not exist @ location.

when try execute same command in shell window, works:

openjdk version "1.8.0_101"

openjdk runtime environment (build 1.8.0_101-b13) openjdk 64-bit server vm (build 25.101-b13, mixed mode)

the command i'm trying execute not java -version more complicated one. however, result same.

i think problem comes php. until have tried increase memory_limit no avail. i've seen people having similar problems solutions proposed don't work.

set memory xms , xmx options java. not php guy have shared links php also, verify if setting both options.

see if can fork process execution of java independent thread , wait

what xms , xmx parameters when starting jvms?

php : settings memory_limits > 1024m not work

ini_set("memory_limit") in php 5.3.3 not working @ all

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
