With pf enabled, I get panics after only a few minutes of light traffic trought the machine. These two I could capture on the console (no dumps written because of mirrored swap): panic: sbsndptr: sockbuf 0xffffff0010005b60 and mbuf 0xffffff0004cdfe00 clashing cpuid = 1 KDB: enter: panic [thread pid 739 tid 100148 ] Stopped at kdb_enter+0x3d: movq $0,0x47ed48(%rip) db> panic: sbflush_internal: cc 60 || mb 0 || mbcnt 0 cpuid = 0 KDB: enter: panic [thread pid 1696 tid 100125 ] Stopped at kdb_enter+0x3d: movq $0,0x47ed48(%rip) db> bt Tracing pid 1696 tid 100125 td 0xffffff000499a000 kdb_enter() at kdb_enter+0x3d panic() at panic+0x17b sbflush_internal() at sbflush_internal+0x64 sbrelease_internal() at sbrelease_internal+0x1c sofree() at sofree+0x107 soclose() at soclose+0x118 _fdrop() at _fdrop+0x23 closef() at closef+0x4c kern_close() at kern_close+0x110 syscall() at syscall+0x1a5 Xfast_syscall() at Xfast_syscall+0xab --- syscall (6, FreeBSD ELF64, close), rip = 0x800d3c89c, rsp = 0x7fffffffcbc8, rbp = 0x1b --- Before enabling pf, the system ran fully stable for two weeks. Disabling pf again (pfctl -d) makes it stable again. Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
