Zookeeper servers will create a lot of sessions when using php_zookeeper under FCGI mode.

[Timandes]

When using php_zookeeper under FCGI mode, it causes servers frequently create and close zookeeper sessions, and generate a lot of log lines.

I'v noticed that the 4th parameter of function zookeeper_init is always set to 0. Is there any better idea to reuse zookeeper session that former script created?
