Hi Sarah,

Not sure if the same cause, but I experienced something like this following
too many open file descriptors/connections.

Cause for me was LDAP connections being opened but never closed by a
client, essentially DDOSing me.

On phone with thumbs, so I can't recall if it was lsof or netstat that
showed the culprit for me, but something like
lsof | grep 10.0.0.0 | wc -l
 (Where 10.0.0.0 was the eyeballed common host). Showed an ever increasing
number of connections until LDAP/389 would bomb and need manually
restarting. We identified the errant client service and stopped that
replica from getting hosed!

Hope this helps,

David
