I am using DEA. But I didn’t found where the container was kept. Is it
compressed and stored somewhere? I also took a look at
/var/vcap/data/dea_next/crashes/id, it only contain the files in “logs”
directory: staging_task.log/stdout.log/stderr.log/env.log, not application
files. We need the files under “app” directory. Also I tried to access
warden as you said. But the warden under /var/vcap/data/warden/depot was
removed immediately after application process was killed.

if you're using DEA's i believe the container stays around on the DEA for
about an hour or so by default before being removed.



assuming you're on a DEA, to investigate, you'd need to know the DEA and
the warden handle to investigate, log in to the DEA as an operator with
bosh, then go the warden depot directory, find the warden handle and
execute bin/wsh from the container handle directory.



see:
http://docs.cloudfoundry.org/running/troubleshooting/troubleshooting-apps.html#access-warden



in diego, removing containers happens right away, but diego is also going
to support ssh for active troubleshooting and could just increase the
memory and attach jvm tools for debugging purposes to troubleshoot.



good luck.

We encountered java out of memory issue in our CF env recently. We had
enabled gc log for the application by setting JAVA_TOOL_OPTIONS:
-Xloggc:gc.log. But when out of memory issue occurred, the application was
stopped and removed. We can’t get gc.log. Is there any way to keep the
gc.log after application crashes? The CF version we are using is 197. Any
advice would be appreciated.
