I executed my project with the following linux command :

nohup java -cp "libs/*:conf" com.yatra.extremesearch.app.ExtremeSearchApp &
on 23rd jan 2013.
This ran perfectly on 23, 24 ,25
It uploads a zip to a machine..
But it didnt upload it after that.

When i do a ps -A| grep java on my linux machine it shows for this process :
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
ytxdist  21368     1 99 1792253 141704 6 Jan23 ?       5-06:02:15 java -cp libs/*:conf -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n com.yatra.e
xtremesearch.app.ExtremeSearchApp


I dont understand this completely.
This means that the process is still running but what could be the issue that it stopped working.

Thanks
