Hmm, in the last couple of weeks I had observed an
amanda backup server failing with strange "out of space"
errors; in some cases the machine was hung (ping was possible,
but console and network login was not possible). kmdb ::memstat
showed that almost 100% of memory was in use by the kernel,
so most likely there is a memory leak somewhere.
Shot in the dark here, but maybe 6786794?
Could be. The bug's submit date matches
the date when I first observed the problem (IIRC) ...
If you have a dump it can easily be verified but first see below
That box is transferring lots of backup data over
tcp, and is also used as an nfs client.
The above bug only happens if you are using a protocol that does not
have it's own flow control like UDP/ICMP etc.
If you provide a crash dump I can look at it and verify if you are
seeing the same problem, or you can easily do so by verifying if the
socket is UDP socket , it has lots of data in it's queue and if it's in
a drain list or not (conn_idl != NULL).
It would be helpful to know which cache is using up the memory.
