Improper/insufficient memory allocation to our JVM as mentioned below.Į.g. (Obviously, for me, this was just a temporary solution I still have an outstanding task to do a more thorough examination of the processes running on that machine to see if there's something that can be done to reduce the nominal memory utilization levels, without having to resort to stopping applications.)įor the error, "error occurred during initialization of vm could not reserve enough space for object heap jboss" Root Cause : Stopping a few other running applications on the machine brought the free memory figures up somewhat: MemTotal: 49300620 kBĪt this point, a new instance of Java would start up okay, and I was able to run my application. Reported that MemFree and SwapFree were both well under 1% of the MemTotal and SwapTotal values, respectively: MemTotal: 49300620 kB Afterwards, double-click the new Instance or press Launch in the right-hand menu. Press Ok to begin downloading the modpack. In the right-hand side, search for and select the modpack you wish to use. Within the new window, select your desired platform, such as Technic or ATLauncher. I found that even just running java -versionĬaused the same error, which established that the problem was not specific to my application. From the main MultiMC page, press Add Instance in the top-left. I was seeing this problem recently on a server running RedHat Enterprise Linux 5.7 with 48 GB of RAM. Sometimes, this error indicates that physical memory and swap on the server actually are fully utilized!
