[Pkg-samba-maint] Bug#780846: samba: panic-action if the inquiring application runs in "threaded" Mode

[tom greisch]

Package: samba
Version: 2:4.1.17+dfsg-2

before some Days i upgraded from Debian 7 to Debian 8. After that i compiled Freeradius Version 2.2.6. If i start Freeradius "single Threaded" everything works fine. In normal "multithread Mode" a samba Logfile "log.wb-<domain>" rapidly fills up with the following Error Messages:



The Error Messages seem to appear only under higher load....
