Sorry for not getting to this earlier. Can you still reproduce the issue? In case you can, please attach your /etc/quagga/ospf6d.conf while at it. Thanks! I worked around that, so I'm not interested anymore. For the record, in some ancient version of Quagga, "redistribute connected" used not to work. It just blankly refused to advertise the default to peers. So, I worked around that by using this construct: router ospf6 redistribute kernel route-map TBD ipv6 prefix-list TBD-prefix permit ::/0 route-map TBD permit 10 match ipv6 address prefix-list TBD-prefix I noticed that NM produces flap in netlink socket and that flap is amplified by ospf6d. So, I went back to "redistribute connected" and it seems working now, so there's no need to redistribute kernel. Using quagga-0.99.22.4-4.fc20.i686 now. |
Description of problem: After a switch from initscripts to NetworkManager, ospf6d started to burn the CPU a lot. See the 293 minutes here: [zaitcev@elanor ~]$ ps auxw | grep ospf quagga 520 0.0 0.3 19848 3144 ? Ss Jul17 0:29 /usr/sbin/ospfd -d -A 127.0.0.1 -f /etc/quagga/ospfd.conf quagga 521 20.9 4.0 56988 40764 ? Rs Jul17 293:02 /usr/sbin/ospf6d -d -A ::1 -f /etc/quagga/ospf6d.conf Version-Release number of selected component (if applicable): quagga-0.99.22.4-4.fc20.i686 How reproducible: Unknown Steps to Reproduce: 1. Install quagga 2. Configure OSPFv6 Actual results: ospf6d burns CPU Expected results: Idling like ospfd Additional info: It looks like ospf6d is getting a constant flap through its Netlink socket: [root@elanor zaitcev]# strace -p 521 Process 521 attached select(1024, [8 11 12 13], [], [], {2, 837289}) = 1 (in [13], left {1, 408018}) clock_gettime(CLOCK_MONOTONIC, {84070, 702498212}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 702706268}) = 0 getrusage(RUSAGE_SELF, {ru_utime={17566, 289000}, ru_stime={63, 815000}, ...}) = 0 gettimeofday({1405691811, 266787}, NULL) = 0 read(13, "\0 \377\2\0\n", 6) = 6 read(13, "\1\20\3\0\1\376\200\0\0\0\0\0\0\306q\376\377\376v \342\1\0\0\0\6", 26) = 26 clock_gettime(CLOCK_MONOTONIC, {84070, 705993471}) = 0 getrusage(RUSAGE_SELF, {ru_utime={17566, 289000}, ru_stime={63, 815000}, ...}) = 0 gettimeofday({1405691811, 269944}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 708144362}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 708764829}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 709307772}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 710438357}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 711054284}) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 711535558}) = 0 getrusage(RUSAGE_SELF, {ru_utime={17566, 289000}, ru_stime={63, 816000}, ...}) = 0 gettimeofday({1405691811, 275072}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {84070, 713230388}) = 0 getrusage(RUSAGE_SELF, {ru_utime={17566, 289000}, ru_stime={63, 816000}, ...}) = 0 gettimeofday({1405691811, 277267}, NULL) = 0 select(1024, [8 11 12 13], [], [], {0, 0}) = 1 (in [13], left {0, 0}) It's possible that NetworkManager does something bad. But without knowing what exactly, I cannot put this issue on Dan's plate. And again, ospfd is not affected.
