Hi folks,
I'm committer at the eclipse project SMILA which uses Apache ZooKeeper.
Lately I was wondering why SMILA isn't available anymore. As I had a look in
log I found this:

In SMILA we're using Apache Zookeeper 3.3.3 from eclipse Orbit.
SMILA was running on a 64 bit Linux OS when the error occurred.
Can anyone tell me what was happening and how I can avoid such behavior?
Thank you and best regards
Peter
