> 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)
