> Kudu servers crash on Graviton3 (aarch64) instances in EC2
> ----------------------------------------------------------
>
> Key: KUDU-3517
> URL: https://issues.apache.org/jira/browse/KUDU-3517
> Project: Kudu
> Issue Type: Bug
> Components: CLI, client, master, tserver
> Affects Versions: 1.17.0
> Environment: Graviton3 instances in EC2
> Reporter: Alexey Serbin
> Assignee: Alexey Serbin
> Priority: Critical
> Labels: ARM, aarch64
>
> Kudu masters and tablet servers built from the source code released with Kudu
> 1.17.0 crash with SIGSEGV when running on Graviton3 (aarch64) instances in
> EC2.
> Upon closer examination, it turned out the problem happens when
> StackCollector tries to symbolize a thread's stack, and an example of the
> trace looked like below. The stack trace has been collected under GDB when
> running a smoke test with the kudu CLI tool: {{kudu perf loadgen
> <master_rpc_addr> \-\-table_num_replicas=3 \-\-num_rows_per_thread=1000000}}:
> {noformat}

> The crash happens with SIGSEGV somewhere in the libunwind code, and that
> looks very similar to what's reported in [this github
> issue|https://github.com/libunwind/libunwind/issues/260].
