Hi, We see daily panics on our production systems (web server, apache running MPM event, openjdk8. Kernel with VIMAGE. Jails using netgraph interfaces [not epair]).
The problem started after the summer. Normal port upgrades seems to be the only difference. The problem occurs with 10.2-p2 kernel as well as 10.1-p4 and 10.1-p15. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203175 Any ideas?
