[jira] [Created] (ARROW-4296) [Plasma] Starting Plasma store with use_one_memory_mapped_file enabled crashes due to improper memory alignment

Anurag Khandelwal created ARROW-4296:
----------------------------------------

             Summary: [Plasma] Starting Plasma store with use_one_memory_mapped_file enabled crashes due to improper memory alignment
                 Key: ARROW-4296
                 URL: https://issues.apache.org/jira/browse/ARROW-4296
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++, Plasma (C++)
    Affects Versions: 0.11.1
            Reporter: Anurag Khandelwal
             Fix For: 0.13.0


Starting Plasma with use_one_memory_mapped_file (-f flag) causes a crash, most likely due to improper memory alignment. This can be resolved by changing the dlmemalign call during initialization to use slightly smaller memory (by ~8KB).
