Can someone please explain the reason on the following code (in asterisk.c, function ast_safe_system()): /* Close file descriptors and launch system command */ for (x = STDERR_FILENO + 1; x < 4096; x++) close(x); Why to close so many descriptors? Thanks in advance ?ric

In Asterisk 1.2.13 in app/app_voicemail.c, line 4700 ext_pass_cmd is checked to decide whether to use vm_change_password or vm_change_password_shell to change a user's password for his voicemail account. I wonder, what is the difference between vm_change_password and vm_change_password_shell - what is that shell? The only reference I found on the Internet was the following bug report:

After restarting Asterisk, the system is normally running until yet. Is there a memory leak in this version? thanks for answer Thomas
