This page contains a list of workarounds for known issues in TeamCity.

Agent running as Windows Service Limitations

When TeamCity build agent is installed as a Windows service, service limitations can affect the builds that the agent is running. At the same time the build can be sensitive to the user it runs under.

Common indicators of the issue are various "Permission denied" or "Access denied" errors during the build process.

The most common service-related issues are:

  • user the service runs under. The user should have enough permissions to perform the build;
  • access to network shares and mapped drives. Services have Windows-imposed restrictions to access the resources;
  • interaction with desktop, headless mode, etc.


If you run TeamCity agent service under "System", try specifying usual user account with necessary permissions granted and restart the service.

If that does not help, try running TeamCity agent via console.

For more investigation steps, see Common Problems.

Logging with Log4J in Your Tests

If you use Log4J logging in your tests, in some cases you may miss Log4J output from your logs. In such cases please do the following:

  • Use Log4J 1.2.12
  • For Log4J 1.2.13+, add the "Follow=true" parameter for console appender, used in Log4J configuration:

Agent Service Can Exit on User Logout under Windows x64

The used version of Java Service Wrapper does not fully support Windows 64 and this causes agent launcher process to be killed on user logout. The agent itself will be function until the next restart (server upgrade or agent properties change).

Subversion-related JVM Crashes

If JVM crashes while executing SVN-related code (e.g. under org.tmatesoft.svn package), you can try to disable it by either:

  • Passing -Dsvnkit.useJNA=false JVM option to the crashing process (server or agent), or
  • Making NTLM support less prioritative by passing -Dsvnkit.http.methods=Basic,Digest,NTLM JVM option.

Anyway, upgrading the JVM used to the latest available version is recommended.

Conflicting Software

Most common indicators of conflicting software are errors like "Access is denied", "Permission denied" or mentioning the file that is present and is writable by the user the agent/build runs under.
Also, certain software running in background (like antiviruses) can significantly slow down build agent operations like sources checkout or artifact publishing.

Certain antivirus software like Kaspersky Internet Security can result in Java process crashes or other misbehavior like inability to access files. Please try running with antivirus software uninstalled before reporting the issue to JetBrains. e.g. see the issue.

Please disable various indexing services. e.g. there might be problems with Windows Indexing Service. See issue for more details. Windows System Restore Feature might also need disabling.

Please also do not install software with background indexing like WinCVS, TortoiseCVS, TortoiseSVN and other Tortoise* products. This applies to server and also to agents if you use agent-side checkout.

Skype software is known to:
1. use port 80 on the system so you might not be able to use TeamCity server using default 80 port.
2. corrupt layout of pages displayed in Internet Explorer. Internet Explorer Skype plugin is to blame. (TW-13052).

Subversion Repositories With NTLM Authorization

If TeamCity has problems connecting to SVN repository, while using NTLM Authentication, add an option to the server JVM options and to the agent options (if you use agent-side checkout):
See a related forum post on this issue.

TeamCity default setting for svnkit.http.methods property is Digest,Basic,Negotiate,NTLM, so this problem should not arise regularly. However, this can also mean that more secure NTLM authentication is not used by default. To enforce using NTLM, add JVM option -Dsvnkit.http.methods=NTLM,Negotiate,Digest,Basic.


Enforced NTLM authentication with TeamCity may be unstable. For instance, you may notice authentication errors after each 5 days of running. One of the ways to workaround this, according to our users, is to use local machine account between TeamCity and VisualSVN server (instead of domain account)

See also a related issue on HTTP Negotiate configuration.

Perforce 2009.2 Performance on Windows

If you run Perforce 2009.2 on Windows you may experience significant slow down. This is an issue with P4 server running on Windows. Please refer to corresponding section in Perforce documentation.

Wrong times for build scheduled triggering (Timezone issues)

Please make sure you use the latest JDK available for your platform (e.g. Oracle JDK download).

There were fixes in JDK 1.5 and 1.6 to address various wrong timezone reporting issues.

Upgrading IntelliJ IDEA May Affect Active Pre-Tested Commits

Before you upgrade to IntelliJ IDEA X (or other IntelliJ X platform products) please make sure you do not have active pre-tested commits, otherwise they will not be able to be committed after upgrade.
This is only relevant if you use directory-based IDEA project (project files are stored under .idea directory).
