Subject: BUG/MEDIUM: tcpcheck: Release temporary small chunk when retrying on http-check
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=cf9694474be1161253e6c70c8ebc22114fbb7e73;p=thirdparty%2Fhaproxy.git

BUG/MEDIUM: tcpcheck: Release temporary small chunk when retrying on http-check

When a http request is sent during an http healthcheck, if an error is
triggered while the output buffer is a small buffer, another attempt is made
with a larger one. When this happens, the temporary chunk used to format
headers must be released.

No backport needed.
