Hi All,
I've been working with Asterisk for 2.5 years now but I am new to the
mailing list. Hoping to get some answers here..
I've written a piece of software to control Asterisk via AMI. I'm able
to login, making outbound calls, receive/record calls, handle digits,
put people into conferences, etc. Everything seems to work well, at a
low to medium call volume.
I've been stress testing the system and found what seems to be a memory
issue within Asterisk. However, after over a day of searching I can't
even find any bug reports or anything to bring me closer to a
solution..but still hoping to find a solution or that someone can help
me find one..
I connect to the AMI successfully. In my test I am making an outbound
call through a sip "device" I configured within sip.conf. This sip
"device" basically connects back into the same Asterisk I am using to
generate the calls.
If I generate outbound calls (i.e.: Via Action: Originate) using a low
call volume everything seems to be fine. e.g.: I can generate 10 calls
and they all go through and complete successfully (with a total of 20
calls bring processed by the same Asterisk, due to both outbound and
inbound calls).
The problem arises If I bombard (i.e.: Write all the Originate requests
within about 7 seconds) the AMI to generate 97 outbound calls (for a
total of 194 channels). The first Originate commands seem to get
processed, but then all of a sudden (after Asterisk seems to have
started processing a good amount of my Originate requests already)
Asterisk seems to reset the AMI interface! Without even having a dropped
connection I receive a new "Asterisk Call Manager/1.3" string and then
previous commands that I issued start coming back with Response: Error
and Message: Permission denied.
I've enabled debugging and here's the security log output when I connect:
[Apr 1 12:43:25] SECURITY[9877] res_security_log.c:
SecurityEvent="SuccessfulAuth",EventTV="1396370605-551714",Severity="Informational",Service="AMI",EventVersion="1",AccountID="username",SessionID="0x7f0c540d96b8",LocalAddress="IPV4/TCP/0.0.0.0/5038",RemoteAddress="IPV4/TCP/192.168.1.62/52139",UsingPassword="0",SessionTV="1396370605-551710"
(This is the time when I am issuing commands, it is accepting and
processing them)
Then all of a sudden (when I receive a new "Asterisk Call Manager/1.3"
string and commands are rejected with "Permission denied") here is what
the log shows:
[Apr 1 12:44:36] SECURITY[9877] res_security_log.c:
SecurityEvent="RequestNotAllowed",EventTV="1396370676-876795",Severity="Error",Service="AMI",EventVersion="1",AccountID="",SessionID="0x7f0c54072968",LocalAddress="IPV4/TCP/0.0.0.0/5038",RemoteAddress="IPV4/TCP/192.168.1.62/52144",RequestType="Action:
Originate",SessionTV="0-0"
(Note: How the AccountID is now empty)
At this same time the CLI shows:
== Manager '*****' logged off from 192.168.1.**
..yet it wasn't my application that disconnected and/or issued an
Action: logoff to Asterisk (my application doesn't even detect a
connection drop, so it seems like Asterisk just logs the manager user out!).
Why did Asterisk all of a sudden reset itself and/or lose reference to
the user I am authenticating with?
Note: My maxcalls setting within asterisk.conf was set to default. I
even tried upping it to 200 and that didn't help. My maxload setting
was untouched/commented out and therefore set to default (no
threshold). I still tried upping it to 6.0, 8.0 and 10.0 to no avail.
I even uncommented minmemfree and set it to 256 (although calling free
-m from a terminal showed their to always be plenty of memory on my system).
Does anyone have an idea how to fix/correct this?
Thank You,
Daniel
