Description Marek Safar 2013-01-04 17:39:24 UTC
When linking large project with many assemblies.

We are probably leaking some file references
Comment 1 Miguel de Icaza [MSFT] 2013-02-12 00:24:04 UTC
Can you point us to a sample that exhibits this problem?

It should be easy once we have the sample to run lsof to find out which file is being kept open for too long.
Comment 2 Marek Safar 2014-09-02 08:14:45 UTC
I don't have sample at hand but it can be quite easily generated. You generate .csproj file with hundreds of reference dlls (for example from mono/mcs/tests).
Comment 3 Sebastien Pouliot 2014-09-02 08:18:31 UTC
I never seen it, neither by myself or being reported. 
If it's easy to reproduce then please attach one and I'll have a look.
Comment 4 Sebastien Pouliot 2015-04-16 11:11:38 UTC
I have never hit that condition, even with very large customer projects. It might be because the underlying issue was fixed (e.g. inside mono) and I just never had a huge project at the time it was an existing issue.

Please re-open, with a test case, if that situation still happens.
