On some systems running Enswitch 3.14 or higher we've noticed Kamailio can crash if there is TCP traffic. The following patch was provided by Daniel-Constantin Mierla to fix it. Apparently the fix went into the 5.1 and 5.2 branches in October 2019.

Replace the exiting functions unload_perl() and perl_reload() from app_perl_mod.c file with the next content:

<pre>
/*
*
*/
int unload_perl(PerlInterpreter *p) {
/* clean and reset everything */
PL_perl_destruct_level = 1;
perl_destruct(p);
perl_free(p);

return 0;
}

/*
* reload function.
* Reinitializes the interpreter. Works, but execution for _all_
* children is difficult.
*/
int perl_reload(void)
{
if(my_perl) {
unload_perl(my_perl);
}
my_perl = parser_init();

#ifdef PERL_EXIT_DESTRUCT_END
PL_exit_flags |= PERL_EXIT_DESTRUCT_END;
#else
#warning Perl 5.8.x should be used. Please upgrade.
#warning This binary will be unsupported.
PL_exit_flags |= PERL_EXIT_EXPECTED;
#endif

if(my_perl) {
LM_DBG("new perl interpreter initialized\n");
return 0;
} else {
LM_CRIT("failed to initialize a new perl interpreter - exiting\n");
exit(-1);
}
}
</pre>
