Ist ein Versuch wert. Kannst du einfach testen:
In der Config bei middleware jeweils andere Strings nutzen („http://localhost“ <http://localhost%e2%80%9c/>, „Http://…“, „HTtp://…“,…) dann werden wie früher 6 parallel Curl Sessions genutzt.
Wenn der Fehler weiterhin auftritt, könntest du auf alten Stand zurückgehen.
Nach deiner Config hast du 6 Channels. D.h. der problematische Thread ist tatsächlich ein Logging Thread. Könnte auch gut Problem innerhalb libcurl sein (ggf. auch timing durch CurlSessionHandler,… verursacht).
Kannst du auch mal ein valgrind machen? (von ca. 1 Min. sollte massig reichen. Braucht kein Crash dabei zu sein.)
