[jira] [Created] (IMPALA-12643) resolve_minidumps.py's minidump_stackwalk call hits OOM on Centos7

Joe McDonnell created IMPALA-12643:
--------------------------------------

             Summary: resolve_minidumps.py's minidump_stackwalk call hits OOM on Centos7
                 Key: IMPALA-12643
                 URL: https://issues.apache.org/jira/browse/IMPALA-12643
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 4.4.0
            Reporter: Joe McDonnell
            Assignee: Joe McDonnell


When looking into fixing IMPALA-11909 to enable running resolve_minidumps.py from finalize.sh, testing on Centos 7 showed that the minidump_stackwalk invocation from resolve_minidumps.py went haywire and used all the system's memory.

resolve_minidumps.py is unique in processing all applicable system libraries. If some system library had corrupt symbols, it could cause minidump_stackwalk to get into an infinite loop.

We should track down the offending library, but we should also run minidump_stackwalk with a limit on its memory usage to avoid using all the system memory.
