[jira] [Commented] (CASSANDRA-15446) Per-thread stack size is too
small on aarch64 CentOS
[ https://issues.apache.org/jira/browse/CASSANDRA-15446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16992744#comment-16992744 ]

-------------------------------------------
This looks related to https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8170655 and https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8173339; the reported JVM is 1.8, does 11 work?

> Project: Cassandra
> Issue Type: Bug
> Components: Local/Config

> Hi all,
> I found an issue when I tried to start cassandra on my aarch64 CentOS7.6, however no errors on Ubuntu. Of course I could increase -Xss in jvm.options to fix it, but this issue also caused Cassandra's docker images from docker hub could not run containers on this OS.
> The information of my current environment and root cause of this issue were shown below.
> *Error*
> The stack size specified is too small, Specify at least 328k
> Error: Could not create the Java Virtual Machine.
> Error: A fatal exception has occurred. Program will exit.
> *Version*
> Cassandra 2.1.21 2.2.15 3.0.19 3.11.5
> *Environment*
> $ lscpu
> Architecture: aarch64
> Byte Order: Little Endian
> $ uname -m
> aarch64
> $ java -version
> openjdk version "1.8.0_181"
> OpenJDK Runtime Environment (build 1.8.0_181-b13)
> OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
> [root@localhost apache-cassandra-3.11.5]# cat /etc/os-release
> $ cat /etc/os-release
> NAME="CentOS Linux"
> VERSION="7 (AltArch)"
> ID="centos"
> ID_LIKE="rhel fedora"
> VERSION_ID="7"
> PRETTY_NAME="CentOS Linux 7 (AltArch)"
> ANSI_COLOR="0;31"
> CPE_NAME="cpe:/o:centos:centos:7"
> HOME_URL="https://www.centos.org/"
> BUG_REPORT_URL="https://bugs.centos.org/"
> *Root Cause*
> Checked openjdk-1.8.0 source code, the min stack size is calculated by StackYellowPage, StackRedPage, StackShadowPage, OS page size. Among those parameters, *default OS page size of aarch64 CentOS 7.6 is 64K, however aarch64 Ubuntu 18.04 and X86 CentOS are both 4K.*
> This difference causes JVM on aarch64 Ubuntu 18.04 needs 164K per-thread stack size, but 328K required on aarch64 CentOS 7.6.
> The formula is
> os::Linux::min_stack_allowed = MAX2(os::Linux::min_stack_allowed,
> (size_t)(StackYellowPages+StackRedPages+StackShadowPages) * Linux::page_size() +
> (2*BytesPerWord COMPILER2_PRESENT(+1)) * Linux::vm_default_page_size());
> *Parameters on aarch64 CentOS7.6*
> intx StackRedPages = 1
> intx StackShadowPages = 1
> intx StackYellowPages = 1
> pageSize 64K
> BytesPerWord 8
> vm_default_page_size 8K
> As a result, we have min_stack_allowed = (1 + 1 + 1) * 64K + (2 * 8 + 1) * 8K = 328K
>
> I could see some similar issues asked for specified achitecture, but no root cause analyzed. I hope this could help you decide proper stack size for all common OS.
> If you have any suggestion, pls let me know.
