Cause

Starting at:
2015-12-16T11:04:42.439, 1.0.0.0.0, root, default, internal, 0, error, 3954, "Failure in send output: - Took Exception", port=808627/skt/50001/10.245.168.17 exception=java.io.IOException: socket not found in LookupService Data=

connection to IP 10.245.168.17 (port 2A) was lost until it gained connection to IP 10.245.158.17 (port 2B)

2015-12-16T11:39:16.346, 1.0.0.0.0, root, default, internal, 0, info, 3913, "Hli connection status change info - host re-connect detected ", newConnection=4101348/000/50001/10.245.158.17 oldConnection=13742421/000/50001/10.245.158.17

It appears that there was a network outage for 35 minutes!!

However, it appears that until 11:47 (time of log snapshot was created) the connection keeps popping up and down for IP 10.245.168.17 as well for IP 10.245.158.17 but no more solid failures since 11:37.

Advised the customer to check the network infrastructure for IP 10.245.168.17 as well for IP 10.245.158.17.

Solution

Customer to perform ACSLS server switch.

After ACSLS server failover from orastkprod1 to orastaprod1, the library started to work again.
