I have multiple technologies running on a single PC like Hadoop, HBase and all. So I have written that many config files. The way I deploy them is by running a for loop over all the configs and deploying them one by one in a separate logstash instance in a thread. These configs output ERROR events to riemann:

```
for(all configs)
do
(bin/logstash -f config &)
finish

```

But this way not a single config works. So I ran a single losgatsh instance on a single config and it worked. Can you please tell me why multiple logstash instances on a single PC are not working?

I already have a single instance of logstash running, it monitors a large number of files and folders and is performing well.I now have a situation where I need to run a completely different configuration file to perform entirely different activities on a completely different set of folders and files on the same server. When I try to run the second instance I get t…
