Problem
If you experience that local analyses in Unix/Linux platforms are very slow, or a long stop before Kiuwan Local Analyzer tries to upload your analysis results to Kiuwan, it is possible that your environment is affected by a well-known bug in some Java Virtual Machines running under UNIX platforms.
The library used for random number generation in Sun's JVM relies on /dev/random by default for UNIX platforms. This can potentially block the JVM on some operating systems /dev/random waits for a certain amount of "noise" to be generated on the host machine before returning a result.
Although Oracle states that this problem has been fixed in Java 6 version, we have been reported that this problem also appears in newer JVM versions like Java 8.
Solution
Follow these steps to fix this problem:
- Exit Kiuwan Local Analyzer.
- Open the $JAVA_HOME/jre/lib/security/java.security file in a text editor.
- Look for the line where
securerandom.sourceproperty is set. Change its value from file:/dev/random to file:/dev/urandom
- Save your change and exit the text editor.
- Run Kiuwan Local Analyzer again.
On some machines, this workaround may not work. If this is your case, try changing the value of the securerandom.source property to:
file:/dev/./urandom
