4gb is way too small
mailbox role requirement is 8gb minimum (exchange 2013) so not surprised you are getting those errors

how many mailboxes?  what version of exchange?
i would start by increasing the memory to 8gb and go from there
if you still have errors, increase to 16gb though again, sizing partially depends on number of mailboxes

even still, it's below the system requirements
i've done 4gb in a test environment and had a lot of issues with exchange services
i increased to 8gb and ran much better
with only 9 mailboxes, 8gb should make this go away
