I have shell scripts like

```
#!/bin/bash
while true;do
   #Code HERE!
   #Pushing Data to DB
   echo "Data to DB"> /root/schip.log 2>&1
done

```

This is script is continuously running and gathering info on server and then sending data to DB(TimeStamp DB). I don't why, sometimes the scripts are dieing. In logs I can't see any thing. In same way, I saw in Python script. Python script like this

```
import <stuff>
while True:
   #Code HERE
   #Push data to DB
   print "Data to DB"

```

So, what could be the reasons?, how do I prevent? and how can I enable the logs(In python and Shell) to know the reason?. Thanks!
