Hi List,
I do geo-replication on a half a dozen volumes or so across several locations. It works fine except for one, our largest volume, a 2x2 distributed-replicated volume with about 40TB of mixed media on it. All of these servers/volumes are running 3.4.6 on CentOS 6.
Every few days, geo-replication on this volume will stop, though the status command shows OK.
I've checked all of the things like clock drift that the geo-rep troubleshooting guide recommends, and everything seems to be fine.
Hopefully without spamming too much logs, here's the last few lines of what I hope might be relevant whenever logging stops.
Any ideas would be much apprediated, I've ben running up against this intermittently for months.
