I am wondering if the behaviour in the picture below is intended? Shouldn’t i stop at 9999? [image]

The problem here is that Dict is not thread safe and you are therefore creating race conditions. You might be interested in this thread: [image] Can dicts be threadsafe? General Usage dict = Dict{Int64,Vector{Float64}}() nentries = 5e5 Threads.@threads for n in 1:nentrie…

I cannot reproduce: julia> d = Dict((i=>i for i=1:9999)); julia> for (i,v) in enumerate(keys(d)) if i==10000 @show i end end Can you provide a MWE? (And please use text and not pics as those cannot be copy pasted)

Thanks for the fast reply! I guess it might be because I am using Threads.@threads beforehand. succeded = Dict{Int,Any}() Threads.@threads for i = 1:1000 succeded[i] = ["a"] end length(keys(succeded)) # returns 806 Does that make sense?
