https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203175 Bug ID: 203175 Summary: Daily kernel crashes on 10.2-p2 using VIMAGE Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: girgen@FreeBSD.org Created attachment 161149 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=161149&action=edit core.txt from /var/crash Hi, We have four jail host machines that all experience this problem. We first suspected hardware, but since all four crash regularly, it should be as software (kernel?) problem. The jail hosts are running 10.2-p2 using GENERIC+VIMAGE using netgraph bridging and they encounter frequent kernel crashes. See attached core.txt - there is also a core dump available if someone want to debug it. The hosts contains around 20 jails half of them running apache2 serving a couple of thousands of users. ZFS on root. The web servers run a java web app (behind apache using mod_jk) process consuming a few GB of ram which frequently executes posix_spawn(3). We also experienced the problem when running on 10.1-p15. The crashes do not appear on 10.1-p4 which we have temporarily reverted to. Could the SCTP kernel memory corruption fix in 10.1-p5 be relevant? Or perhaps the 10.1-p15 TCP resource exhaustion one? -- You are receiving this mail because: You are the assignee for the bug.
