Max size of --snaplen

[0xdeaddc0de]

I'm trying to dump the content of a sys_write using a chisel. After a bit of research i've found that --snaplen increase the max size for capturing I/O opreration, but even with this i'm capped at 41512. Is there a way of increasing this ? My chisel looks like this

function starts_with(str)
    return str:sub(1, #elf_magic) == elf_magic
end
-- Event parsing callback
function on_event()
    if evt.field(ftype) == syscallname and evt.field(fdir) == "<" then
        local content = evt.field(fcontent)
        print("------------------------")
        print(string.format("size : %d",#content))
        print("------------------------")
        if starts_with(content) == true then
            count = count + 1
            print(string.format("[+]Dumping elf number %d",count))
            local file_name = "elf_dump_" .. count
            local file = io.open(file_name, "w")
            if file then
                file:write(content)
                file:close()
            else
                print("Failed to open file for writing:", file_name)
            end
        end
    end

    return true
end
