Lamb I still could reproduce the issue on stg.openshift.com (devenv-stage_1175). you could access my app on STG: http://aero-111.stg.rhcloud.com/ Status: ON_QA → ASSIGNED Verified: FailedQA [reply] [−] Private Comment 3 Florian Traverse 2015-08-21 11:16:48 EDT I face the same issue on an aerogear that was running for months, some days ago it became unreliable, yet not as much as today(we could ssh). We thought at the time there was a full, but in fact we had OutOfMemory errors, so we used the JVM_HEAP_RATIO=0.6 env var to give it a bit more, then it crashed again, we have set JVM_HEAP_RATIO=0.8, then it worked for 2 hours, and it never recovered from it. I cannot even ssh / snapshot it to put it on a bigger gear. I've tried several things, including setting JVM_HEAP_RATIO=0.1 and JVM_HEAP_RATIO=0.0 to make the app crash but so I could ssh and snapshot, but it did not work, still. This aerogear is in production. If I create a new aerogear on another account(a free one) I could ssh during the afternoon, yet it had several issues, simple commands like "env | grep MYSQL" returned 6 errors that it couldn't fork, lately I could not snapshot this one either nor could I ssh it anymore : ``` $> rhc snapshot save Pulling down a snapshot of application 'aerogear' to aerogear.tar.gz ... Error in trying to save snapshot. You can try to save manually by running: ssh 55d7083a0c1e667f64000181@aerogear-alloci.rhcloud.com 'snapshot' > aerogear.tar.gz $> rhc ssh Connecting to 55d7083a0c1e667f64000181@aerogear-alloci.rhcloud.com ...
