JVM Crashes

On a rare occasion of the TeamCity server or agent process terminating unexpectedly with no apparent reason, it can happen that this is caused by a Java runtime crash.
If this happens, the Oracle JVM creates a file named hs_err_pid*.log in the working directory of the process. The working directory can be <TeamCity server or agent home>/bin or other like C:\Windows\SysWOW64. You can also search the disk for the recent files with "hs_err_pid" in the name.

Please send this file to us for investigation and consider updating the JVM for the server (or for agents) to the latest version available.

If you get the "There is insufficient memory for the Java Runtime Environment to continue. Native memory allocation (malloc) failed to allocate ..." message with the crash or in the crash report file, make sure to switch to 64 bits JVM or reduce -Xmx setting not to increase 1200m, see details in the memory configuration section.
