Context: mono/mono#11706 Context: #2357 Context: https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android/1239/console Sometimes a Jenkins build will timeout when executing the xamarin-android unit tests. The timeout *appears* to occur when `mono` is used to execute a process, the process "finishes," but the process never actually *exits*, thus "hanging". For example, [consider this build log fragment][0] (with timestamps): 23:37:48 Build succeeded. 23:37:48 0 Warning(s) 23:37:48 0 Error(s) 23:37:48 23:37:48 Time Elapsed 01:23:14.60 02:37:48 Build timed out (after 180 minutes). Marking the build as aborted. The "Build succeeded" message comes from an `msbuild` invocation. Once `msbuild` finished, we would expect it's process to exit. *It didn't*. Instead, the underlying `mono` process is *not* exiting, presumably deadlocked, until the overall job times out and is killed. Attempt to help identify the hang by using a "debug" mono/2018-08 system mono, built from [Mono PR #11706][1], which prints out additional messages around child process use: diff --git a/mono/metadata/w32process-unix.c b/mono/metadata/w32process-unix.c index 2db5dea7a705..fbd4731cacb2 100644 --- a/mono/metadata/w32process-unix.c +++ b/mono/metadata/w32process-unix.c @@ -2096,7 +2095,7 @@ process_create (const gunichar2 *appname, const gunichar2 *cmdline, if (argv) g_strfreev (argv); - mono_trace (G_LOG_LEVEL_DEBUG, MONO_TRACE_IO_LAYER_PROCESS, "%s: returning handle %p for pid %d", __func__, handle, pid); + g_printerr ("XXX-MONO: %s: returning handle %p for pid %d from %d\n", __func__, handle, pid, getpid()); This will hopefully allow @lewurm to continue investigations.
