PM2 启动管理多个 app 出现 id 混乱是神马情况？

首先我使用了不同的启动方式：

pm2 start index.js pm2 start process.json 

启动了 3 个 app ，第一次执行是正常的：

$ pm2 list ┌──────────┬────┬──────┬───────┬────────┬─────────┬────────┬─────────────┬──────────┐ │ App name │ id │ mode │ pid │ status │ restart │ uptime │ memory │ watching │ ├──────────┼────┼──────┼───────┼────────┼─────────┼────────┼─────────────┼──────────┤ │ index │ 0 │ fork │ 48337 │ online │ 0 │ 2m │ 23.746 MB │ disabled │ │ lianj-pc │ 1 │ fork │ 48871 │ online │ 1 │ 20s │ 74.781 MB │ disabled │ │ demo │ 2 │ fork │ 48889 │ online │ 1 │ 20s │ 64.785 MB │ disabled │ └──────────┴────┴──────┴───────┴────────┴─────────┴────────┴─────────────┴──────────┘ 

其中 index 启动端口为 8001 ，其他两个分别为 9000 ， 8000 。 ** index id=0, lianj-pc id=1, demo id=2 **

那么问题来了，当我再次单独执行 pm2 start process.json 时，启动出现了问题：

请看我在日志中加了***的部分，启动 id 和 app name 的对应已经发生混乱，都对应到了 index 的 id 上去，结果就是 index 不断重启，但是又因为重复绑定端口而报错，日志如下：

M2 App [lianj-pc] with id [0] and pid [66856], exited with code [255] via signal [SIGINT] PM2 Starting execution sequence in -fork mode- for app name:lianj-pc id:0 PM2 App name:lianj-pc id:0 online lianj-pc-0 Error: listen EADDRINUSE 127.0.0.1:8001 lianj-pc-0 at Object.exports._errnoException (util.js:870:11) lianj-pc-0 at exports._exceptionWithHostPort (util.js:893:20) lianj-pc-0 at Server._listen2 (net.js:1234:14) lianj-pc-0 at listen (net.js:1270:10) lianj-pc-0 at net.js:1379:9 lianj-pc-0 at GetAddrInfoReqWrap.asyncCallback [as callback] (dns.js:64:16) lianj-pc-0 at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:83:10) 

想从 Google 问个究竟，却始终查不出什么，不知道大家有没有遇到的，目前来看会不会就是不能混合使用启动方式呢？
