Is there a means of 'catching' a Connection Timeout

Long store short I'm pulling data from a Postgres database and pushing data
structures to a shared queue so that the data structures can be turned into
Mutations, but I keep getting Connection Timeouts and I was curious to know
if there was a means of catching these timeouts so that if I'm still in the
process pushing stuff to the Accumulo Cluster I can have the program
continue.

Try taking a peek at the zookeeper server logs around that time period.
 Maybe that will have some clues as to why the zookeeper client is losing
its connection.

I'm currently using Accumulo version 1.4.3, Hadoop version 1.2.0, and
Zookeeper 3.3.6.

Here's a stack trace of what's going down:

13/08/15 15:00:17 INFO zookeeper.ClientCnxn: Client session timed out, have
not heard from server in 29577ms for sessionid 0x14073acbb2c687f, closing
socket connection and attempting reconnect
13/08/15 15:00:18 INFO zookeeper.ClientCnxn: Opening socket connection to
server SERVER
13/08/15 15:00:18 INFO zookeeper.ClientCnxn: Socket connection established
to SERVER, initiating session
13/08/15 15:00:18 INFO zookeeper.ClientCnxn: Session establishment complete
on server SERVER, sessionid = 0x14073acbb2c687f, negotiated timeout = 40000
13/08/15 15:11:40 INFO zookeeper.ClientCnxn: Client session timed out, have
not heard from server in 682606ms for sessionid 0x14073acbb2c687f, closing
socket connection and attempting reconnect
13/08/15 15:11:41 INFO zookeeper.ClientCnxn: Opening socket connection to
server argus-1/192.168.20.100:2181
13/08/15 15:11:43 INFO zookeeper.ClientCnxn: Socket connection established
to argus-1/192.168.20.100:2181, initiating session
13/08/15 15:11:43 INFO zookeeper.ClientCnxn: EventThread shut down
13/08/15 15:11:43 INFO zookeeper.ClientCnxn: Unable to reconnect to
ZooKeeper service, session 0x14073acbb2c687f has expired, closing socket
connection

I get the EventThread shut down and then my program cannot continue.

Do you have an available stack trace? And, which version of
Accumulo/Hadoop/Zookeeper are you running?
