请问使用etop监控输出Erlang top got garbage是什么意思20

小弟刚使用erlang,做一个广播服务器,有1w多个连接, 遇到两个问题:

1.使用etop监控程序时发现输出很多Erlang top got garbage,是不是内存泄露了呢?
Erlang top got garbage {trace_ts,<4897.30040.98>,out,
                                 {gen,wait_resp_mon,3},
                                 {1263,783491,9919}}
Erlang top got garbage {trace_ts,<4897.44.0>,out,
                                 {ets,select_trap,1},
                                 {1263,783491,55033}}
Erlang top got garbage {trace_ts,<4897.30043.98>,out,
                                 {prim_inet,accept0,2},
                                 {1263,783491,55055}}
Erlang top got garbage {trace_ts,<4897.19490.97>,out,
                                 {gen,wait_resp_mon,3},
                                 {1263,783491,58450}}

2.看到很多crash日志,内容为:

是不是很gen_tcp:recv(Sock, 0)这里没有处理超时的错误呢,我看很多代码也没有做处理.

以上两个问题,各位有经验的老大能否给小弟个提示,谢谢!
