Aspose Email unhandled exceptions

Hello,

I use Aspose.Email in a window service application. The service create many threads and every thread use Aspose.Email to download email (POP3 and IMAP).
Some customers have reported to me that sometimes the service stops. Checking the Windows event viewer I see two types of recurring errors. This is the log:

I’m using the 5.3.0.0 version. Someone have already reported such kind of errors? I might update the libraries, but I would only do if they include fixes for such problems.

Thanks.
