    We have a Parallels Cloud server with 5 Nodes.
    After updating PCS 6.0 Update 8 from Hotfix 2 to Hotfix, 8 we have noticed a big difference in RAM used.
    Until hotfix 2 there was plenty of RAM available.
    After updating to hotfix 8, we see that almost all available RAM is used, and actually it is cached:
    # free -m
                 total       used       free     shared    buffers     cached
    Mem:        257783     238623      19159       1061      17385     187037
    -/+ buffers/cache:      34199     223583
    Swap:        51199      13921      37278
    As far as I understand, it is not bad that the Ram is used from cache, but I would like to know if this happened because of the update, or there is some other explanation.

    I read the release notes of every update but I didn't find anything about ram usage.

    I vote for 'some other explanation'.
    We are not aware about any changes in memory consumption.
    Files from hotfix 8 itself are good candidate for disk cache as well.
