Intermittent threading errors with FindLogEntries

[davidpene]

When running tests in parallel, we intermittently get this exception:

System.InvalidOperationException : Collection was modified; enumeration operation may not execute.
   at System.Collections.Generic.List`1.Enumerator.MoveNextRare()
   at WireMock.Server.FluentMockServer.FindLogEntries(IRequestMatcher[] matchers) in /Server/FluentMockServer.LogEntries.cs:line 42

I'm trying to reliably reproduce this issue but could use some more information.
Are you running tests in parallel using the same WireMockServer instance? Or does each test create a new instance?

Additionally,

at WireMock.Server.FluentMockServer.FindLogEntries(IRequestMatcher[] matchers) in /Server/FluentMockServer.LogEntries.cs:line 42

does not point to a line of code in my version of the repo. Are you running the latest nuget package?

[davidpene]

We're running tests in parallel and using a static wiremock server to mock a single "api". We're using version 1.0.7. I'll bump to the latest 1.1.9.0 and let you know if the issue continues.

Hey David, did updating the nuget package resolve your issue?

Hey @NoahLerner the issue was intermittent and it hasn't shown up again, so it may have been solved. Happy to close this issue and I'll reopen if I see it again.
Cheers
