Cisco Bug: CSCuw48499 - QEMU coredump: qemu_thread_create: Resource temporarily unavailable
Sep 28, 2018
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
Symptom: With 9.5.2 ASA image loaded on ASA 5506, 5508, or 5516 with Firepower SFR enabled - several hours after SFR is in Up/Up state QEMU coredumps and restarts SFR with following: qemu: qemu_thread_create: Resource temporarily unavailable On ASA console following is seen: Also, on console: ciscoasa# /asa/scripts/run_qemu_kvm.sh: line 111: 3729 Aborted (core dumped) /usr/bin/qemu-system-x86_64 -nographic -m $SYS_RAM -smp $NUM_CORES -hda $DISK_IMAGE $HDD_PARAM $ISO_IMAGE -enable-kvm -net nic,macaddr=$CP_MAC_ADDRESS,model=$DRIVER,vlan=1,name=cp,addr=$CP_BUS_ADDR -net tap,ifname=tap3,vlan=1,script=no,downscript=no -net nic,macaddr=$MGMT_MAC,model=$DRIVER,vlan=2,name=mgmt,addr=$MGT_BUS_ADDR -net tap,ifname=tap4,vlan=2,script=no,downscript=no -net nic,model=e1000,name=data,addr=$DATA_BUS_ADDR -serial pipe:$LOG_PIPE -serial unix:$CONSOLE_SOCKET,server,nowait -fdb $META_INFO -monitor /dev/null $IPS_NO_REBOOT $ASA_SHMEM_CMD $ASA_SHMEM_CHAR_DEV $CPP_KVM_SHMEM_CMD $QEMU_MEM_PATH > $LOG_PIPE 2>&1 Recently we have also seen re-images of SFR fail with the following error: DB error - will retry: Cannot connect to DB If the entire console log is viewed with "show module sfr log console", you will see the "qemu: qemu_thread_create: Resource temporarily unavailable" error multiple times prior to the DB error. So for any SFR re-image issue, make sure they are running an ASA version that includes the fix for this bug. Conditions: No particular trigger. Just load 9.5.2 on ASA 5506, 5508, or 5516 with Firepower SFR enabled. Recently seen in multiple cases for re-image of SFR 6.1.
