I have a microservice (springboot) inside a docker container. I am also passing a long list of JVM flags so that the program runs on that VM environment to test the latency values with each flag combination.
I am using this command to start the container:
docker run --rm --name factorialorialContainer -p 8080:8080 -e JAVA_OPTIONS="$(cat /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/flags.txt)" suleka96/factorial:latest
The flags.txt looks like this:
-XX:-ResizePLAB -XX:+ResizeOldPLAB -XX:+AlwaysPreTouch -XX:-ParallelRefProcEnabled -XX:-ParallelRefProcBalancingEnabled -XX:-UseTLAB -XX:-ResizeTLAB -XX:+ZeroTLAB -XX:+FastTLABRefill -XX:-UseAutoGCSelectPolicy -XX:-UseAdaptiveSizePolicy -XX:+UsePSAdaptiveSurvivorSizePolicy -XX:-UseAdaptiveGenerationSizePolicyAtMinorCollection -XX:+UseAdaptiveGenerationSizePolicyAtMajorCollection -XX:-UseAdaptiveSizePolicyWithSystemGC -XX:+UseAdaptiveGCBoundary -XX:+UseAdaptiveSizePolicyFootprintGoal -XX:YoungPLABSize=4354 -XX:OldPLABSize=1141 -XX:GCTaskTimeStampEntries=255 -XX:TargetPLABWastePct=5 -XX:PLABWeight=73 -XX:OldPLABWeight=21 -XX:MarkStackSize=5927008 -XX:MarkStackSizeMax=579749070 -XX:RefDiscoveryPolicy=1 -XX:InitiatingHeapOccupancyPercent=49 -XX:ErgoHeapSizeLimit=0 -XX:MaxRAMFraction=3 -XX:MinRAMFraction=3 -XX:InitialRAMFraction=74 -XX:AutoGCSelectPauseMillis=2934 -XX:AdaptiveSizeThroughPutPolicy=0 -XX:AdaptiveSizePausePolicy=0 -XX:AdaptiveSizePolicyInitializingSteps=24 -XX:AdaptiveSizePolicyOutputInterval=4060 -XX:AdaptiveSizePolicyWeight=11 -XX:AdaptiveTimeWeight=69 -XX:PausePadding=39200 -XX:PromotedPadding=3 -XX:SurvivorPadding=1 -XX:ThresholdTolerance=11 -XX:AdaptiveSizePolicyCollectionCostMargin=68 -XX:YoungGenerationSizeIncrement=28 -XX:YoungGenerationSizeSupplement=81 -XX:YoungGenerationSizeSupplementDecay=9 -XX:TenuredGenerationSizeIncrement=48 -XX:TenuredGenerationSizeSupplement=63 -XX:TenuredGenerationSizeSupplementDecay=2 -XX:MaxGCPauseMillis=16157174462788231168 -XX:GCPauseIntervalMillis=3009 -XX:GCTimeRatio=77 -XX:AdaptiveSizeDecrementScaleFactor=4 -XX:AdaptiveSizeMajorGCDecayTimeScale=9 -XX:MinSurvivorRatio=4 -XX:InitialSurvivorRatio=4 -XX:BaseFootPrintEstimate=463170010 -XX:GCHeapFreeLimit=4 -XX:ProcessDistributionStride=4 -Xms338224019 -Xmx1103493303
when I run the above-mentioned docker command I get the below error:

-XX:+ZeroTLAB选项已损坏。请不要使用此标志。我猜这里涉及到随机选项生成器是为了性能调优。虽然这个想法本身是好的，而且有一些已知的案例1，2当机器学习与贝叶斯优化帮助找到JVM选项的更好的值时，这里的关键点是在实验中只包括那些你很好地理解含义和含义的选项。
此外，实验还应注意每个选项的合理范围，以及相关选项之间的相互关系。
然而，上面的选项列表看起来完全是随机的，没有多大意义（也许，除了JVM测试）。毫不奇怪，这样的配置可能会产生不可预测的结果，包括JVM崩溃。

非常类似，我试图运行cassandra，它立即出错，“退出”就是这样。退出代码是131，这是一些java类型的错误。这些是标志：
在小心地删除了几个标志之后，它变成了“-XX：+AlwaysPreTouch”。
叹了口气。
