ldirectord spinning on SIGPIPE

Hi,

I'm running a pair of load balancers here, both Debian etch,
kernel 2.6.18 and heartbeat/ldirectord 2.0.7. ldirectord has 33
virtual configurations in its config for several services, some
tcp ports and a few on firewall marks. They are in the "high
capacity, high availability and load balancing" configuration with
direct routing[0].

The setup has been running stable for at least a couple of years
now. Things don't change that frequently.

Recently the ldirectord process has stopped working fairly
frequently. Symptoms are that services are not being checked, and
the ipvs tables are not updated. The ldirectord process is still
running, but stracing it gives, for example:

--- SIGPIPE (Broken pipe) @ 0 (0) ---
write(4, "\27\3\1\0\33\r\310Q\347\n\230\375@\370 \372\263\322\256"..., 32) = -1 EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
write(4, "\27\3\1\0\33\r\310Q\347\n\230\375@\370 \372\263\322\256"..., 32) = -1 EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
write(4, "\27\3\1\0\33\r\310Q\347\n\230\375@\370 \372\263\322\256"..., 32) = -1 EPIPE (Broken pipe)

...in a loop continuously.

I've found one post from this list a while back[1] where this was
experienced, but this patch is in the version that we are using.

The server here is currently in this situation; I can leave it
like this for a few hours if there is anything I can do to help
debug, but obviously need to restart ldirectord soon so that it
can work properly.

Any ideas?

Thanks!

Matthew
