How do I resolve the Jenkins error: "Process leaked file descriptors" when using the lscm command?

We have a Jenkins job that calls the lscm Windows batch script to log in to RTC. When running the Jenkins job however, we receive the error: "Process leaked file descriptors". This error also appears when running any other lscm command like logout and load. I've tried putting the lscm commands into a separate batch file but I get the same result. Any help would be appreciated. Thanks.

Based on some comment about how this error gets generated, it seems the behavior is expected? https://wiki.jenkins-ci.org/display/JENKINS/Spawning+processes+from+build Basically when you run lscm, it does spawn a process (the daemon). This may make Jenkins to believe it is a "problem", hence the error. To verify this, you can try replace "lscm" with "scm". The difference between these two commands is mainly the daemon - no daemon for "scm".

Using the "scm" command seems to work now, thanks. Are there any downsides to using "scm" rather than "lscm"?

scm is slower, because it needs to reload all the eclipse libraries to execute the command (instead of sending the request to a running daemon, as is done by lscm).  But otherwise, the functionality is identical.

Hi Donald,
It seems to be Jenkins issue. I found similar issue here: http://stackoverflow.com/questions/17024441/process-leaked-file-descriptors-error-on-jenkins which refers to https://wiki.jenkins-ci.org/display/JENKINS/Spawning+processes+from+build

Let us know if it helps.
