Bug ID: 1144270 Summary: SBT doesn't start correctly in some 32-bit machines due to low memory Product: Fedora Version: 20 Component: sbt Assignee: willb@redhat.com Reporter: dugucloud@qq.com QA Contact: extras-qa@fedoraproject.org CC: java-sig-commits@lists.fedoraproject.org, s@shk.io, willb@redhat.com
Description of problem: When starting SBT, Java reports cannot start VM because it cannot reserve enough heap.
Version-Release number of selected component (if applicable): 0.13.1
How reproducible: Every time on my machine.
Steps to Reproduce: Run command sbt in console and see the console output.
Actual results: ''' $ sbt Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. '''
Expected results: SBT works fine.
Additional info: My machine is 32-bit. When I start SBT, my memory usage is 0.8 GiB / 2.5 GiB, swap usage 0 GiB / 3.8GiB.
But after I modified the memory settings of Java in my SBT script (/usr/bin/sbt), I can run it. These are the last few lines of my modified:
''' export BASE_CLASSPATH=$(build-classpath scala ivy sbt ${JLINE} jansi test-interface sbinary) export JAVA_OPTS="-Xms256m -Xmx1024m -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxHeapSize=1000m -XX:MaxPermSize=256m"
java ${JAVA_OPTS} -Dfedora.sbt.boot.dir=${SBT_BOOT_DIR} -Dfedora.sbt.ivy.dir=${SBT_IVY_DIR} -Dsbt.boot.properties=${SBT_BOOT_PROPERTIES} -cp ${BASE_CLASSPATH} xsbt.boot.Boot "$@" '''

--- Comment #1 from Fedora End Of Life endoflife@fedoraproject.org --- This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
