Hi All,

I have connection pool from which Redis Contexts are shared across different threads. HiRedis Hangs on RedisBufferRead() with following bt:

#0 0x0000000808bd6d0c in read () from /lib/libc.so.7

#1 0x000000080859a830 in read () from /lib/libthr.so.3

#2 0x0000000803c01b07 in redisBufferRead () from ./lib/libhiredis.so.0.11

#3 0x0000000803c03006 in redisGetReply () from ./lib/libhiredis.so.0.11

#4 0x0000000803c03084 in redisvCommand () from ./lib/libhiredis.so.0.11

#5 0x0000000806d99486 in RedisUtil::run_redis_query_set (command=@0x7ffff73b5350) at RedisUtil.cpp:60

#6 0x0000000806d9e422 in RedisUtil::set_redis_session (sess_id=@0x7ffff73b5d60, scope_map_temp=<value optimized out>, is_external=false) at RedisUtil.cpp:122

I could find online that this issue could happen if same Context is used by two threads at same time. Since I am using a pool, this should not have caused the issue. Any leads would be appreciated.
