How to clear hs_err_pid log file in home directory

Question

I have lots of log file in my home directory:

hs_err_pid2326.log
hs_err_pid2416.log

I believe it is a java error log file, how to remove it and stop creating them?

Java version:

[kelvin@localhost ~]$ java -version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) Server VM (build 17.0-b16, mixed mode

Answer 1

They are created if and when the JVM crashes; they're analogous to a core file, but contain a lot of Java-specific information. They're just text files, and you can delete them like you would any other files:

$ rm ~/hs_err_pid*.log

You can stop creating them by no longer crashing the JVM. Normally, such crashes are rare. Look at the files themselves in a text editor and they will contain some info about their origins.

Answer 2

These are Java crash (core) dump log files. Identify which Java process creates them by tracing and monitoring the PID.
