quagga/bgpd: memory leak? any ideas?

In last two weeks i have strange memory problems with quagga/bgpd on some of our routers

After about a day bgpd eats all of router memory (2G, 3G) on different routers with different quagga versions. (0.99.15,0.99.18 and 0.99.20)

All of the routers are connected to TWO Internet borders with FULL bgp ~400k routes

all are 32bit architecture
CPU Quad Core Q9550
total used free shared buffers cached
Mem: 1954 1574 380 0 18 19
-/+ buffers/cache: 1536 418
Swap: 1953 3 1949

quagga 8185 0.0 3.9 82952 79004 ? Ss Apr08 1:29 /usr/sbin/zebra -d -f /etc/quagga/zebra.conf -l 255 --pid_file /var/run/quagga/zebra.pid
quagga 8200 4.3 66.3 1332408 1328320 ? Rs Apr08 68:52 /usr/sbin/bgpd -d -f /etc/quagga/bgpd.conf --pid_file /var/run/quagga/bgpd.pid

After i reset bgpd process it frees all the memory and work fine for 1 or 2 days.

i tried community delete,extra attributes and couple of memory leak patches with no effect.

What that temporary memory mean and why it is so high ?

They all worked for about an year with no problems, but in last week i reset them every couple of days
updated some of routers to last quagga version but with no effect..

Any ideas how to fix this strange memory issue ?

Can you post your configuration for bgpd?

Not sure which patches you tried, but I still need to apply this one
(its in the FreeBSD port) for bgpd not to chew up all memory

Re: quagga/bgpd: memory leak? any ideas? [In reply to]

@Mike exactly this patch, no effect

@Jorge It seems to be OK with this patch, I patched two of my routers 0.99.18 and 0.99.20, temporary memory stays 1 and memory usage looks OK(very nice indeed). I will wait 12 hours to confirm you and if everything is OK i will apply it to all of my routers.

Please, test this version if you can. It should be more efficient than the
other I sent before because avoids useless conversion to/from string
representation of the nexthop.

On my limited testing seems to do the right thing too.

Re: quagga/bgpd: memory leak? any ideas? [In reply to]

@Jorge, I confirm this patch works also! Thank you very much!!!

I applied it to all of my routers, temporary memory now stays 1, no memory leak problems, 18 hours so far, memory usage has never been so low :).
Everything is working nice and smooth.
Hope this patch will be merged to master branch.

Thank you very much, Jorge! You are the man :)

You're welcome. The fact is I've been working on optimizing the bgpd daemon and
I have the code fresh on my mind.
