killing an infinite loop in java

阅读更多关于 killing an infinite loop in java

问题 I am using a third-party library to process a large number of data sets. The process very occasionally goes into an infinite loop (or is blocked - don't know why and can't get into the code). I'd like to kill this after a set time and continue to the next case. A simple example is: for (Object data : dataList) { Object result = TheirLibrary.processData(data); store(result); } processData normally takes 1 second max. I'd like to set a timer which kills processData() after , say, 10 seconds

问题 I'd like to restart one of many Node.js processes I have running on my server. If I run ps ax | grep node I get a list of all my Node proccesses but it doesn't tell me which port they're on. How do I kill the one running on port 3000 (for instance). What is a good way to manage multiple Node processes? 回答1: If you run: $ netstat -anp 2> /dev/null | grep :3000 You should see something like: tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN 5902/node In this case the 5902 is the pid. You can use something

Return code when OS kills your process

问题 I've wanted to test if with multiply processes I'm able to use more than 4GB of ram on 32bit O.S (mine: Ubuntu with 1GB ram). So I've written a small program that mallocs slightly less then 1GB, and do some action on that array, and ran 5 instances of this program vie forks. The thing is, that I suspect that O.S killed 4 of them, and only one survived and displayed it's "PID: I've finished"). (I've tried it with small arrays and got 5 printing, also when I look at the running processes with

阅读更多关于 How to kill a nohup process?

I executed the following command $ nohup ./tests.run.pl 0 & now when I try to kill it (and the executions that are started from this script) using $ kill -0 <process_id> it does not work. How can I kill a nohupped process and the processes that runs via the nohupped script? Thanks kill -0 does not kill the process. It just checks if you could send a signal to it. Simply kill pid , and if that doesn't work, try kill -9 pid . Simply kill <pid> which will send a SIGTERM , which nohup won't ignore. You should not send a SIGKILL first as that gives the process no chance to recover; you should try

If my app encounters a particular error, I want to end my app without any trace of it remaining in the system. I have already seen many threads on this topic, specially these two.
