Denis, the problem is described in https://issues.apache.org/jira/browse/IGNITE-9638 It is not specific to Continuous Queries. It occurs when user code starts new threads a lot and calls Ignite APIs from there (which is not common, since idiomatic .NET code should use built-in thread pool instead).
I investigated it thoroughly last year and, unfortunately, did not find a clean, cross-platform solution - see my comment in Jira. We'll have to develop a fix for every platform (Linux, Windows, Mac) separately in C or C++, compile native binaries and ship them as part of Ignite.NET or as a dependency.
