X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=b637934677634886383916c417e1be148ee0c7ad;p=collectd.git rrd plugin: Fix writing of long values. The buffer provided for value_list_to_string() was not long enough to fit a timestamp and a negative value using exponent and maximum precision of the gauge format.
