Just to add further details, we have 3 HP SIM Repositories running, 1 of then has HP SIM installed on it and this is the one using all the memory.
Repository 1 - Version 7.4.0.0, HP SIM installed as well version 7.3.0.0, Physical host with Windows 2008 R2 Enterprise, 16 GB memory installed, using 15.6 GB of memory.
Repository 2 - Version 7.3.0.0, doesn't have HP SIM installed, VM with Windows 2012 R2 Standard, 8 GB memory allocated, using 2.1 Gb only.
Repository 3 - Version 7.1.0.910, doesn't have HP SIM installed, VM with Windows 2008 R2 Standard, 4 GB memory allocated, using 1.78 Gb only.
Maybe I should separate the Repository from the SIM application for Repository 1 ?
