Hey,
We have a website that is in asp and the website basically encrypts the credit card info and then through remoting the information is passed to a different server where it gets decrypted before reaching mainframe. We have used Singleton class for decryption for better performance but it looks like the decryption process fails once in a while when multiple web requests tries to access the decrypt what I mean is as the load is increased the decryption fails.
How can I resolve this issue. Any help will be appreciated.
Thanks in advance.

You can either ensure that you are locking where required or you move to Single-Call.
Depending on what you are doing this may make single-call faster than a thread-safe singleton.
