Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
I'm getting the following sets of log messages about 2-3 times per day. Performance seems unaffected, but I'm worried. No other applications report any network outages (including heartbeat, which is running on the same link). Any ideas on this?
