Hi,
I have created a bug for this:
http://bugzilla.xamarin.com/show_bug.cgi?id=1741
I know there are similar bugs reported earlier in bugzilla, please give me a
solution for this.
This is critical, and if we can not resolve this, our product is gone, we can
not proceed at all.
Here is the detail again:
We are downloading lot of image files by calling web method once for each
file in loop. We receive the file as stream of bytes.
When tested, for a download of about 50~200 files, after few 20~30 files the
web service call fails and the app crashes, while downloading any random
file(not specific to any file).
File sizes are normally 0.5MB to 4 MB, and we have already set timeout etc,
as given below:
binding.SendTimeout = new TimeSpan(0, 20, 0);
binding.MaxReceivedMessageSize = 2147483647;
binding.MaxBufferSize = 2147483647;
svc.Proxy = new ProjectCentreServiceClient(binding, endpoint);
I have monitored the error and mostly this appears:
