buffer overflow detected : terminated**
*=====================
In old forum discussion noted that there might be something related to tls bug and IPv6
In current config Pv6 is disabled.
tls version is 1.7.16
gnutls version is 3.6.14
piaware version is 6.1
Until 20.11.2022 after 888 days there was no such buffer overflow termination.
Also noted that not all reconnections exhibit this behavior… Here are all “connection lost” events with reconnections to adept server since 20.11 and only in 3 cases buffer overflow happens.
It may be assumed that some of “connection lost” are caused by local internet provider and others are from far end i.e adept server and just then something happens with buffer.
