Hello, I’ve encountered a few crashes over the last few weeks. Has anyone seen this before?

#2

Do you mind providing more information, like how often it happens, what seems to trigger it, and mainly, some code that reproduces it?


#3

Gladly, it seems to happen about once a week, there doesn’t seem to be anything unusual happening at the time with Aerospike or the client system. We have two UDFs, one for updating and adding new data and one for an aggregate query. They are both running constantly so I can’t really be certain which might be related from the client code side. We’re using the Java client and Aerospike is running on AWS, with two m4.large instances with io1 volumes.

local function counters_merge(a, b)
    -- add counters and take larger of times
    local r = list {
        math.max(a[1], b[1]),
        a[2] + b[2],
        math.max(a[3], b[3]),
        a[4] + b[4],
        math.max(a[5], b[5]),
        a[6] +  b[6] }
    return r
end

local function merge_maps(a, b)
    local r = map.merge(a, b, counters_merge)
    return r
end

local function extract_counters(r)
    return r['counters']
end

function sum(stream, s, e)
    local filter = filter_user_and_day(s, e)
    return stream:filter(filter):map(extract_counters):aggregate(map(), merge_maps):reduce(merge_maps)
end

local function counters_merge(a, b)
    -- add counters and take larger of times
    local r = list {
        math.max(a[1], b[1]),
        a[2] + b[2],
        math.max(a[3], b[3]),
        a[4] + b[4],
        math.max(a[5], b[5]),
        a[6] +  b[6] }
    return r
end

function update(record, i, day, x, wt, wc, ct, cc, c1t, c1c)
    local param_list = list { wt, wc, ct, cc, c1t, c1c }
    if aerospike:exists(record) == false then
        record['i'] = user
        record['day'] = day
        record['counters'] = map()
        aerospike:create(record)
    end

    if record.counters[x] == nil then
        trace("x was null")
        record.counters[x] = param_list
    else
        record.counters[x] = counters_merge(record.counters[x], param_list)
    end

    -- you need to "touch" then counters recored otherwise aerospike doesn't know it was updated
    record.counters = record.counters

    aerospike:update(record)

    return 1
end

#4

I also am facing a similiar problem. On execution of lua the server crashes Lua scripts. I am using Node js client.

   function app(rec, a, b, new_record, isodate)
        local c = rec["c"]
        if (not c)
        then
            c = map.create(1)
        end
        local f = c[a]
        local to_add = 1
        if (f)
        then
            to_add = 0
        end
        rec['m.e'] = rec['m.e'] + to_add
        rec['m.updated_on'] = isodate
        c[a] = new_record
        rec["c"] = c
        aerospike:update(rec)
        return 0
    end
    
    function cdd(rec, a, isodate)
        local c = rec["c"]
        local d = c[a]
        if(not d)
        then
            return 0
        end
    
        rec['m.e'] = rec['m.e'] - 1
        rec['m.updated_on'] = isodate
        c[a] = nil
        map.remove(c, a)
        rec["c"] = c
        aerospike:update(rec)
        return 0
    end
    
    function eff(rec, a, b, isodate)
        local c = rec["c"]
        if (not c)
        then
            return 0
        end
        rec['m.updated_on'] = isodate
        local g = c[a]
        g['b'] = b
        g['updated_on'] = isodate
        c[a] = g
        rec["c"] = c
        aerospike:update(rec)
        return 0
    end
