Kapil Thangavelu updated ZOOKEEPER-768:
---------------------------------------
Summary: zkpython segfault on close (assertion error in io thread)
(was: zkpython segfault (assertion error in io thread))
Description: While trying to create a test case showing slow average
add_auth, i stumbled upon a test case that reliably segfaults for me, albeit
with variable amount of iterations (anwhere from 0 to 20 typically). fwiw, I've
got about 220 processes in my test environment (ubuntu lucid 10.04). The test
case opens a connection, adds authentication to it, and closes the connection,
in a loop. I'm including the sample program and the gdb stack traces from the
core file. I can upload the core file if thats helpful. (was: While trying to
