From bash(1):
    The maximum number of lines contained in the history file. When this
    variable is assigned a value, the history file is truncated, if
    necessary, to contain no more than that number of lines. The default
    value is 500. The history file is also truncated to this size after
    writing it when an interactive shell exits.

Setting HISTFILESIZE to 0 might therefore do what you describe seeing.
