Can you please me understand what caused this issue?
Maybe : from the looks of it, your tomcat uses some (non-tomcat) mechanism to connect to
an external Microsoft SQL Server, and that is not working (anymore).
It does not seem to have anything to do with Tomcat per se.
What happened after that looks very much like a death spiral into runaway memory
consumption and vain attempts by the JVM at reclaiming some badly needed memory, until it
gives up in despair...
