SQLA - Memory Issue

Hello All,
The SQLA is throwing the following error at random times and it is really very painful as it needs the whole SQLA to be restarted(closed and opened a new). It is really very helpful if there is a permanent or workaround available.
Error Message found at SQLAError file:
SQLA Version:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
