Description of problem:<br />
Corosync crashes at least once per day on either of the two nodes. The<br />
configuration:<br />
<br />
totem {<br />
version: 2<br />
secauth: off<br />
cluster_name: sio-db<br />
transport: udpu<br />
rrp_mode: passive<br />
}<br />

node {<br />
ring0_addr: sio-c01-db01<br />
ring1_addr: sio-c01-db01a<br />

}<br />
node {<br />
ring0_addr: sio-c01-db02<br />

<br />
logging {<br />
to_syslog: yes<br />
debug: on<br />
}<br />
<br />
Debug shows nothing intersting. Ring0 is connected through a tinc VPN which <br />
introduces latency, but otherwise is stable. Ring1 is directly connected<br />
via patchcable.<br />
