As my kernel had started to lock up periodically and I don't have hands-on access to that machine, I enabled WITNESS. So these started to pop up: -- cut here -- --- syscall (97, FreeBSD ELF64, socket), rip = 0x80070427c, rsp = 0x7fffffffe8c8, rbp = 0x516348 --- uma_zalloc_arg: zone "16" with the following non-sleepable locks held: exclusive rw udp r = 0 (0xffffffff8064c928) locked @ /usr/src/sys/netinet/udp_usrreq.c:1125 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2a witness_warn() at witness_warn+0x241 uma_zalloc_arg() at uma_zalloc_arg+0x290 malloc() at malloc+0x5c getenv() at getenv+0x93 getenv_quad() at getenv_quad+0x13 getenv_int() at getenv_int+0x15 udp_inpcb_init() at udp_inpcb_init+0x1f slab_zalloc() at slab_zalloc+0x1ad uma_zone_slab() at uma_zone_slab+0xb4 uma_zalloc_arg() at uma_zalloc_arg+0x31d in_pcballoc() at in_pcballoc+0x38 udp_attach() at udp_attach+0x57 socreate() at socreate+0x14f socket() at socket+0x8a syscall() at syscall+0x1a9 Xfast_syscall() at Xfast_syscall+0xab --- syscall (97, FreeBSD ELF64, socket), rip = 0x80070427c, rsp = 0x7fffffffe8c8, rbp = 0x516348 --- -- and here -- I tried to see whether bz@ had this one on his page, but his website is currently being migrated and the list of LORs was unavailable.
