Application uses SFTP .NET assembly is terminated (General questions)

Hi,

I use WeOnlyDo.Client.SFTP version 2.1.1.3 and WeOnlyDo.Security.Cryptography.KeyManager version 1.0.1.10 to push/pull files to remote SFTP server. The .NET application which uses these assemblies faily intermittendly once in a while. When it fails the application is being killed with an termination code of e0004743 (TerminateProcess+0xb). This is in production and I do handle exception in my application code but still this happens. Can you please help to resolve this problem ASAP.

Thanks
Selvam.
