servers stuck in initializing

this has been happening on servers for at least the last 30 minutes, possibly longer, on all the new instances. they start, run all the scripts, but stay in initializing forever. i grabbed some information from the scalarizr log below.

farm 13308
role 46201
server 53415126-942e-4896-9686-bf1fb2e5bace

    still having this issue. this is a big problem in terms of being able to scale up to meet increasing demand.

    One of BeforeHostUp scripts lead to Scalarizr restart

    2014-12-18 22:58:21,641+00:00 - INFO - scalarizr.handlers - Executing 6 BeforeHostUp script(s)
    2014-12-18 22:58:33,355+00:00 - INFO - - [pid: 2447] Starting scalarizr 2.12.5

    It's not supported. Scalarizr couldn't be safely restarted before Server will reach Running state.

    Its getting the unrecoverable error before any of the scripts are executed. Also, the same scripts are used in two other farms and not generating the same errors.  The scripts do actually execute correctly and the server is in a good condition otherwise, but it's useless unless it gets out of "initializing"

    From debug log it's visible, that Scalarizr executes script, then killed by someone, and started again

    the error started happening at the same time that the scalarizr version was
    increased on this farm from 2.12.4 to 2.12.5. also, our other farms
    running the same script are not having this issue. the script in question
    does nothing related to scalarizr at all. here are the contents:

      apt-get update
      apt-get install -y openssl libssl1.0.0

    There are several app servers on this farm, initialized fine with 2.12.5. For example and

    I'm sure this issue is not related to 2.12.5, and i agree that apt-get update should't be the cause.

    Maybe crobtab? or any of other tasks restart Scalarizr?

    there are 2 that succeeded. there were many many others that failed, and i
    killed them. there is currently a server sitting in this state now that i
    have not yet killed. i have been giving them 30 minutes, then terminating

    As an experiment, can you please try to disable all BeforeHostUp scripts and see if instance initialize or not. If yes, then start to turn them on one by one to see which one causing trouble and then we will help you to find the reason. If instances will fail to initialize without scripts, then will try to dig down and find what restarts scalarizr.

    Initially I mentioned HostUp scripts, but meant BeforeHostUp ones.

    would it be ok to make them hostup scripts instead of removing them? its a
    pain to remove them completely and then put them back in.

    The server started. I don't understand why my scripts, which work on other
    farms with scalarizr version 3.1.24 work, and previously worked on this
    farm with 2.12.4, but don't work on this farm with 2.12.5.

    I suppose this solution will work, having the scripts run on HostUp, but
    isn't optimal

    Instead of removing them, you can just set Execution target to "DO NOT EXECUTE".

    Execute them on HostUp would solve issue. But I still would advise you to find out what causing scalarizr restart.

    its something dependent on that one version of scalarizr. there is quite a
    bit in those scripts, and startup times are so long, it'll take way too
    long to pinpoint it, so i'll leave it for now.
