Load SSL DLL's fail on sending email

[JohanR]

Hi,

Every now and again I get this error on sending emails.

There is a procedure that sends emails from a list, it runs through the list and STARTS a few threads at a time, each thread sends a different mail.
The first mail and subsequent mails gets this error.
Restarting the application works and the mails go through fine on restart.
As far as I can see I have the correct DLL's in the folder.

Any ideas on why this might happen, this procedure should not fail or rely on re-start as it's not being monitored or managed by a user.


thanks

Johan

It should only load the DLL's once.
So I recommend perhaps just doing 1 thread to "warm it up" then it should be ok for multiple threads after that.
