Please see this stack trace: https://tc-oss.intelliplan.net/viewLog.html?buildId=111&buildTypeId=Suave_BuildIt&tab=buildLog or in TL;DR mode:

[13:45:59][Step 2/3] Shutting down finalizer thread timed out.
[13:45:59][Step 2/3] Bad call to mono_mutex_lock result 22

Log in with guest/guest if you want to see all build parameters to reproduce the error.

Here's a possibly related bug https://github.com/SuaveIO/suave/issues/94; it might be zlib interop corrupting some runtime state, as these happen together.

This commit: 2d346db7e464347fc3bcdd437342e8bf089279a0 in https://github.com/SuaveIO/suave/commit/2d346db7e464347fc3bcdd437342e8bf089279a0 reproduces the problem most the times.

The link above to the CI server is for 3.2.8, x64 CentOS 6.5.

I can also reproduce it on my mac, with 3.4.0, OS X v10.8.5.

Expected outcome: no crash in GC.

Background on suave: a multi-threaded async web server in F# aiming to be cross-platform. If you want to run the tests yourself, just start the code that compiles to a CLR executable from https://github.com/SuaveIO/suave/tree/master/Tests.

Not getting this with latest mono anymore.
