    Description

      We recently upgraded zookeeper from 3.2.1 to 3.3.1, now we are seeing less client deadlock on session expiration, which is a definite plus!

      Unfortunately we are seeing memory leak that requires our zk clients to be restarted every half-day. Valgrind result:

      ==8804== 25 (12 direct, 13 indirect) bytes in 1 blocks are definitely lost in loss record 255 of 670
      ==8804== at 0x4021C42: calloc (vg_replace_malloc.c:418)
      ==8804== by 0x5047B42: parse_acls (zookeeper.c:369)
      ==8804== by 0x5047EF6: pyzoo_create (zookeeper.c:1009)
      ==8804== by 0x40786CC: PyCFunction_Call (in /usr/lib/libpython2.4.so.1.0)
      ==8804== by 0x40B31DC: PyEval_EvalFrame (in /usr/lib/libpython2.4.so.1.0)
      ==8804== by 0x40B4485: PyEval_EvalCodeEx (in /usr/lib/libpython2.4.so.1.0)
