Hello Core,
looking at bad things happening and logs from our network switches it
seems that the CA client that runs on the IOC does a name resolve
request whenever any record with a link pointing into nirwana (aka an
unconnected link) is being processed.
Example: on IOC1, there are 100 records (scanned at 10 Hz) pointing to
100 other records sitting on IOC2. As soon as IOC2 is down, IOC1
broadcasts a name resolution request for those 100 channels 10 times a
second.
Is that true? Is that smart?
Confused,
Ralph
(trying to find out why a single IOC going halfway down drives _all_ our
IOCs into 95+ percent of cpu usage)
