问题
I have WebJob running continuously using the 1.0.0 WebJobs SDK.
Here is configuration code.
public static void Main()
{
var config = new JobHostConfiguration();
config.Queues.MaxDequeueCount = 1;
config.Queues.BatchSize = 1;
var host = new JobHost(config);
host.RunAndBlock();
}
Here is my job function signature.
public static void HuntVkusniyBlogRss([QueueTrigger("queue-rss")] string message,
DateTimeOffset expirationTime,
DateTimeOffset insertionTime,
DateTimeOffset nextVisibleTime,
string id,
string popReceipt,
int dequeueCount,
string queueTrigger,
CloudStorageAccount cloudStorageAccount,
TextWriter log)
{
...
}
I expect that after running function successefully, message is deleted from triggering queue. But I am getting function run more then once.
Logging shows that it is run on every nextVisibleTime and dequeueCount is incrementing each time.
UPD: It looks like error happens after function is executed. Here is logs from webjob dashboard:

回答1:
I ran into this problem because container are not always auto-created. So, I created:
azure-jobs-host-output
azure-webjobs-hosts
回答2:
I had the exact same problem, I had a separate storage account for the data and logs. If I used the same storage account for both this bug stops.
回答3:
Check the webjobs SDK version, if that is lower than the 1.1.1.0, then ensure you are with latest version.
so it should be like below, we had the same issue with webjobs sdk version 1.0.1.0 and upgrading this to latest one fixed the issue.
- Microsoft.Azure.WebJobs.dll (in our case current version was 1.0.1.0 and we need 1.1.1.0)
- Microsoft.WindowsAzure.Storage.dll (current version is 4.2.1.0, we need (≥ 4.3.0 && ≤ 5.0.2).
