strange logging: [main-EventThread-EventThread...SendThread()]

hi all,

I'm connecting to zookeeper 3.3.3 from tomcat. and caught some weird
logging recently after running some task that forks and joins threads many
times.  after the task completed, zookeeper starts to give strange
loggings. The server still got very high load on both CPUs but 0% on
processes. memory usage is stable but virtual memory size kept growing (but
not causing any problem)..
The log shows like this once a few seconds.

service, session 0x13a9e07caa815fe has expired, closing socket connection
