Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

-110 -> is an errno value of 110

#define ETIMEDOUT 110 /* Connection timed out */

Your SyncTarget node seems not to be able to handler this. 

I would never configure DRBD to use more than 30% of my RAW 
disc trhoughput for synchronisation. -- This is just my oppinion.
Since we got the AL high resync rates are not necessary at all...
