    Default Java command generates defunct on Solaris sparc 8

    Hi everyone,

    I'm working on continous integration with Jenkins.

    I’m facing an issue while connecting a slave (solaris sparc 8) with Jenkins ver. 1.532.2

    This slave is connected via the option “Launch slave via execution of command on the Master”.

    Connection is established with:

    - Connecting to the slave via FTP
    - Executing java command:
    /jdk1.6.0_24/bin/java -jar slave.jar -jnlpUrl file:///...

    This way, the connection is successful.

    However, the slave gets extremely slow and a lot of defunct process are generated. It’s a real problem because no jobs can run on this slave.

    I can’t find the reason why there is zombie generation, the parent of these defunct is the java command (PPID) ....
    Can you please help on this? Any idea is welcomed.

    Thanks you.



    Best regards.

    I can’t find the reason why there is zombie generation, the parent of these defunct is the java command (PPID) ....

    A core file is also generated (even if the java process is still running) with some lines like these:

    FF330000 32K read/exec /udev/pac/jdk1.6.0_24/jre/lib/sparc/jli/libjli.so
    FF346000 16K read/write/exec /udev/pac/jdk1.6.0_24/jre/lib/sparc/jli/libjli.so

    Thanks you.
