* ctdb-locking: Reduce logging in case of contentionAmitay Isaacs2017-06-193-22/+157
| | | | | | | | | | | | | | | Currently, every lock helper will log a message if it cannot get a lock. This can spam the logs and overwhelm syslog if there are hundreds of lock helpers waiting for contended record. Instead keep track of the record for which we have already logged once with specific timeout interval. If we get timeout interval larger than the previously logged interval, then log again once. This will reduce the amount of logs for contended records to a single log entry per 10 seconds per record.
