> ReplaceText, when scheduled to run with multiple Concurrent Tasks, and using a Replacement Strategy of "Regular Expression" or "Literal Replace" can result in content being corrupted by sharing a single buffer (byte[]) between threads.
> The issue is far more likely to occur with multiple Concurrent Tasks, but it may be possible to trigger when using a single Concurrent Task.
