You can tell strace to filter out uninteresting events. For example "-e trace=process" will only include system calls which involve process management. You
can also filter on specific system calls, e.g. "-e trace=chmod". Without filtering, strace output quickly becomes unusable. /Jesper From: cdt-dev-bounces@xxxxxxxxxxx [mailto:cdt-dev-bounces@xxxxxxxxxxx]
On Behalf Of Steve Lorimer Hmm - my strace output is up to 2 GB now without the issue cropping up... not sure this is feasible.

strace to have it follow child processes? Eclipse will spawn a helper process called "spawner" which does the actual system call to start the subprocess, and there is no mention of this in your strace output. /Jesper From:

$ strace eclipse 2> /tmp/eclipse.strace.out It seems to stop during launching and then the following message is the last returned wait4(15567, log4j:WARN No appenders could be found for logger (org.eclipse.jgit.util.FS). log4j:WARN Please initialize the log4j system properly. Please see log attached Any insight greatly appreciated! Thanks Steve
