Linux Kernel 3.4.111 with glibc 2.22, 32bit, not virtualized.

Assuming that bind would report dropped queries, I guess it is the latter. Regarding the suggestion made by Tony Finch about too many TCP connections in the TIME_WAIT status: That would have been a good explanation. But I do not see more than 200 TCP connections in TIME_WAIT status when the problem occurs and not more than 5000 TCP/UDP connections with port 53. cu, brunni -- ++ Michael Brunnbauer ++ netEstate GmbH ++ Geisenhausener Straße 11a ++ 81379 München ++ Tel +49 89 32 19 77 80 ++ Fax +49 89 32 19 77 89 ++ E-Mail bru...@netestate.de ++ http://www.netestate.de/ ++ ++ Sitz: München, HRB Nr.142452 (Handelsregister B München) ++ USt-IdNr.
