Pervasive PSQL verson 11.xx is installed but server shows 6 out of 32 gig ram allocated being used.??? No Microsoft SQL.

Data is going to a BackBlaze online account. OS is Windows Server 2008 R2. Server is barely used. it is the prior ERP server that is only access for historical use. It is a virtual on ESXI. It backed up last month and all daily partials for this month.
Hmm. Ok, I will look at the MS link right after lunch. Might be something there. Thanks for the info.
