Fixes

• Fix issue with vector cache limit introduced in v1.15.1 by @etiennedi in #2240
  v1.15.1 changed the default for the vector cache limit to the maximum value of an int64. This could lead to isssues when an implicit int->float conversion happened. Depending on the architecture, this would resolve in either an error or an overflow, thus leading to a negative cache limit.
  This version fixes this by explicitly handling the error, and setting the default to a safer value (1 Trillion), which will effectively act as unlimited.
