rlm_perl module crash on high load, need to restart service

[Imdad Hasan]

Thanks Alen,

This is my perl script code which is a socket client for the swoole TCP
socket server.


use strict;
use vars qw(%RAD_REQUEST %RAD_REPLY %RAD_CHECK);
use IO::Socket;
use locale;
use POSIX;
use JSON;

use Sys::Syslog;

# our (%RAD_REQUEST, %RAD_REPLY, %RAD_CHECK, %RAD_STATE);

setlocale(LC_ALL, 'C');


use constant RLM_MODULE_REJECT=>    0;#  /* immediately reject the request
*/
use constant RLM_MODULE_FAIL=>      1;#  /* module failed, don't reply */
use constant RLM_MODULE_OK=>        2;#  /* the module is OK, continue */
use constant RLM_MODULE_HANDLED=>   3;#  /* the module handled the request,
so stop. */
use constant RLM_MODULE_INVALID=>   4;#  /* the module considers the
request invalid. */
use constant RLM_MODULE_USERLOCK=>  5;#  /* reject the request (user is
locked out) */
use constant RLM_MODULE_NOTFOUND=>  6;#  /* user not found */
use constant RLM_MODULE_NOOP=>      7;#  /* module succeeded without doing
anything */
use constant RLM_MODULE_UPDATED=>   8;#  /* OK (pairs modified) */
use constant RLM_MODULE_NUMCODES=>  9;#  /* How many return codes there are
*/

Guide me if i made a mistake here..
