            Bug ID: 27934
           Summary: failure to attach statement
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: uprobes
          Assignee: systemtap at sourceware dot org
          Reporter: avi@cloudius-systems.com
  Target Milestone: ---

Trying a script:

#!/usr/bin/stap

# usage: task_latency.stap process_name

global histogram

probe process(@1).mark("reactor_run_tasks_single_start") {
    histogram[tid(), $arg1] +=3D 1
}

probe end {
    foreach ([shard, vtable] in histogram) {
        printf("%d/0x%x: %d\n", shard, vtable, histogram[shard, vtable])
    }
}


I get

WARNING: probe
process("/home/avi/scylla/build/release/test/perf/perf_simple_query_g").sta=
tement(0x302b6a3)
at inode-offset 2014175825:00000000856e063f registration error (rc -524)


And no results. What is registration error -524?
