Kapil Thangavelu commented on ZOOKEEPER-768: -------------------------------------------- i've uploaded the core file here http://kapilt.com/files/zkpython-segfault-on-close-core.bz2 a little more poking around in gdb, shows the packet to be a ping one. (gdb) print hdr $8 = {xid = -2, zxid = 181, err = 0} > zkpython segfault on close (assertion error in io thread) > --------------------------------------------------------- > > Key: ZOOKEEPER-768 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-768 > Project: Zookeeper > Issue Type: Bug > Components: contrib-bindings > Affects Versions: 3.4.0 > Environment: ubuntu lucid (10.04), zookeeper trunk (java/c/zkpython) > Reporter: Kapil Thangavelu > Attachments: zkpython-segfault-client-log.txt, > zkpython-segfault-stack-traces.txt, zkpython-segfault.py > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
