Hi all,
I'm running ipf v3.4.29 on a FreeBSD
4.7-RELEASE-p9 box, and having
mbuf cluster problems. It appears that
ipnat may not be releasing mbuf clusters
after use, if thats possible?
I have 65000 mbuf clusters, and the box
is on a 256K link - its not overloaded.
Whenever IPNat is under use, the mbuf
clusters continue to rise until reaching the
limit, and the box halting. I'm seeing the
mbuf cluster usage rise by about 5000
every 30 minutes, which is quite quickly...
At night when the load goes, it stops rising,
but doesnt flush at all. The next morning the
mbuf cluster value is still just as high (but
has not risen)...
Is there a way I can tell for sure if its IpNat
that is using up all the mbuf clusters? I need
to find out for sure that it is actually ipnat
before I can really try solve the problem.
Is there a history at all of problems like this?
Because I certainly cant find any information
about it.
Any help as to how to problem shoot this
would be most appreciated,
Thanks
Dave
