I had a problem:
SipCallback callback = new SipCallback();
MySipStack mSipStack = new MySipStack(callback, realm, impi, impu);
MyMessagingSession shortMessageSession = new MyMessagingSession(mSipStack, this.remotePartyUri);
shortMessageSession.SendTextMessage(this.msgtextbox.Text);
shortMessageSession.Dispose();
As described above,i can't send messages and I got the following error:
file: "..\..\..\..\..\..\doubango\branches\2.0\doubango\tinyNET\src\tnet_utils.c"
line: "357"
MSG: Not implemented on your OS
***ERROR: function: "tsip_api_message_send_message()"
file: "..\..\..\..\..\..\doubango\branches\2.0\doubango\tinySIP\src\api\tsip_api_message.c"
line: "69"
MSG: Stack not started.
*INFO: *** SIP Session destroyed ***
How to successfully send a message？

I have a django based web application where I am using Kafka to process some orders. Now I use Celery Workers to assign a Kafka Consumer to each topics. Each Kafka Consumer is assigned to a Kafka topic in the form of a Kafka tasks. However after a day or so, when I am submitting a task I am getting the following error :
_mysql.connection.query(self, query)
_mysql_exceptions.OperationalError: (2006, 'MySQL server has gone away')
The above exception was the direct cause of the following exception:
Below is how my tasks.py file looks like :
#shared_task
def init_kafka_consumer(topic):
try:
if topic is None:
raise Exception("Topic is none, unable to initialize kafka consumer")
logger.info("Spawning new task to subscribe to topic")
params = []
params.append(topic)
background_thread = Thread(target=sunscribe_consumer, args=params)
background_thread.start()
except Exception :
logger.exception("An exception occurred while reading message from kafka")
def sunscribe_consumer(topic) :
try:
if topic is None:
raise Exception("Topic is none, unable to initialize kafka consumer")
conf = {'bootstrap.servers': "localhost:9092", 'group.id': 'test', 'session.timeout.ms': 6000,
'auto.offset.reset': 'earliest'}
c = Consumer(conf)
logger.info("Subscribing consumer to topic "+str(topic[0]))
c.subscribe(topic)
# Read messages from Kafka
try:
while True:
msg = c.poll(timeout=1.0)
if msg is None:
continue
if msg.error():
raise KafkaException(msg.error())
else:
try:
objs = serializers.deserialize("json", msg.value())
for obj in objs:
order = obj.object
order = BuyOrder.objects.get(id=order.id) #Getting an error while accessing DB
if order.is_pushed_to_kafka :
return
order.is_pushed_to_kafka = True
order.save()
from web3 import HTTPProvider, Web3, exceptions
w3 = Web3(HTTPProvider(INFURA_MAIN_NET_ETH_URL))
processBuyerPayout(order,w3)
except Exception :
logger.exception("An exception occurred while de-serializing message")
except Exception :
logger.exception("An exception occurred while reading message from kafka")
finally:
c.close()
except Exception :
logger.exception("An exception occurred while reading message from kafka")
Is there anyway that I could check if database connection exists as soon as a task is received and if not, I can re-establish the connection?
According to https://github.com/celery/django-celery-results/issues/58#issuecomment-418413369
and comments above putting this code:
from django.db import close_old_connections
close_old_connections()
which is closing old connection and opening new one inside your task should helps.
I am uploading a file to Alibaba Cloud - OSS bucket. Have correct access key and secret key.
Using oss-sdk-php through yii2, Getting Error

Unable to get exact issue, any help would be appreciated.

I am having issue with box-sdk (https://github.com/box/box-windows-sdk-v2) upload API.
Issue :
When try to upload large file (more than 3MB) (file less than 3mb works great.)
Upload api fails and throws below exception.
Error :
ToString :

Code that is generating error :
using (Task<BoxFile> uploadTask = boxClient.FilesManager.UploadAsync(boxFileRequest, spStream))
{
BoxFile newFile = uploadTask.Result;
}
Try to use timeout parameter in UploadAsync method:
boxFile = Client.FilesManager.UploadAsync(req, fs, null, new TimeSpan(1, 0, 0)).Result;
When my Grails application crashes, it shows the error and the stacktrace on the error page because the error.gsp page has the following snippet <g:renderException exception="${exception}" />. However nothing gets logged in the log file.
How can I change this? because for the production application I plan to remove the renderException because I don't want users to see the entire stacktrace.
My log4j settings are as follows:
appenders {
rollingFile name:'catalinaOut', maxFileSize:1024, fileName:"${System.properties.getProperty('catalina.home')}/logs/mylog.log"
}

I'm running the app in development as grails run-app
I use these settings for console and file based logging. You can remove stdout if you don't want/need console. Just copy all your error classes in the corresponding list.
log4j = {
def loggerPattern = '%d %-5p >> %m%n'
def errorClasses = [] // add more classes if needed
def infoClasses = ['grails.app.controllers.myController'] // add more classes if needed
def debugClasses = [] // add more classes if needed
appenders {
console name:'stdout', layout:pattern(conversionPattern: loggerPattern)
rollingFile name: "file", maxFileSize: 1024, file: "./tmp/logs/logger.log", layout:pattern(conversionPattern: loggerPattern)
}
error stdout: errorClasses, file: errorClasses
info stdout: infoClasses, file: infoClasses
debug stdout: debugClasses, file: debugClasses
}
I use Mule 3.x
I have a code that tests MuleClient connectivity.
This test is ok and works proper way:
public void testHello() throws Exception
{
MuleClient client = new MuleClient(muleContext);
MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
assertNotNull(result);
assertNull(result.getExceptionPayload());
assertFalse(result.getPayload() instanceof NullPayload);
//TODO Assert the correct data has been received
assertEquals("hello", result.getPayloadAsString());
}
But this tes is not ok - it fail with an connection exceptions:
public void testHello_with_Spring() throws Exception {
MuleClient client = new MuleClient("mule-config-test.xml");
client.getMuleContext().start();
//it fails here
MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
assertNotNull(result);
assertNull(result.getExceptionPayload());
assertFalse(result.getPayload() instanceof NullPayload);
//TODO Assert the correct data has been received
assertEquals("hello", result.getPayloadAsString());
}
The 'mule-config-test.xml' is used in both tests, the path for this file is ok, i checked.
This is error message I have in the end:

I think the problem is in what you're not showing: testHello_with_Spring() is probably executing while Mule is already running. The second Mule you're starting in it then port-conflicts with the other one.
Are testHello() and testHello_with_Spring() in the same test suite? If yes, seeing that testHello() relies on an already running Mule, I'd say that would be the cause of port conflict for testHello_with_Spring().
