Konstantin Kolinko created DAEMON-252:
-----------------------------------------
Summary: [procrun] Thread Dump command fails with "Unable to open
the Event Mutex"
Key: DAEMON-252
URL: https://issues.apache.org/jira/browse/DAEMON-252
Project: Commons Daemon
Issue Type: Bug
Components: Procrun
Affects Versions: 1.0.10
Environment: Windows 7 SP1, Windows XP SP3
Reporter: Konstantin Kolinko
Priority: Minor
The issue was reported on users<at>tomcat.a.o. I've confirmed that it is
reproducible.
The thread:
http://tomcat.markmail.org/thread/r74penaeymdmeeic
http://marc.info/?t=133839294900003&r=1&w=2
To reproduce:
1. Install Tomcat 7.0.27. It contains Commons Daemon procrun 1.0.10.0.
I tested with 32-bit versions on Windows 7 and Windows XP.
2. Start the service and service monitor application. The latter has to be run
as administrator under Windows 7.
3. Right-click tray icon and select "Thread Dump" from popup menu.
4. A message box appears:
---------------------------
Application System Error
---------------------------
Не удается найти указанный файл.
Unable to open the Event Mutex
---------------------------
ОК
---------------------------
The first line of the message comes from OS and means "The system can not find
the file specified."
Enabling debug logging does not provide any additional information. The issue
is reproducible under Windows XP, so UAC is not involved.
According to the original reporter a workaround is use the "jstack" utility
that comes with JDK. Other recipes can be found in [Tomcat
