Unity jenkins simultaneous build hangs on shader compiling

Hello, I'm using jenkins CI on windows machine and doing android build on it. My build process hangs when 2 and more build requests are simultaneously raised.

unityBuild says that every 5 minutes to console output, without any progression.

 Timed out connecting pipe to external process: C:/Program Files (x86)/Unity/Editor/Data/Tools/UnityShaderCompiler.exe
 UnityEditor.BuildPipeline:BuildPlayerInternalNoCheck(String[], String, BuildTarget, BuildOptions, Boolean, UInt32&)
 UnityEditor.BuildPipeline:BuildPlayerInternal(String[], String, BuildTarget, BuildOptions, UInt32&) (at C:\buildslave\unity\build\artifacts\EditorGenerated\BuildPipeline.cs:164)
 UnityEditor.BuildPipeline:BuildPlayer(String[], String, BuildTarget, BuildOptions) (at C:\buildslave\unity\build\artifacts\EditorGenerated\BuildPipeline.cs:108)


 Failed to launch shader compiler! C:/Program Files (x86)/Unity/Editor/Data/Tools/UnityShaderCompiler.exe

This problem was not occured when jenkins was installed on mac. Any ideas?

Thanks.
