It's critical that you review the Junos OS dates and milestones to determine whether Juniper still supports your Junos version. If your installed version is approaching its end of support from Juniper, then Upgrade your vSRX immediately to maintain full support.

All versions before 19.4R3-S2 are prone to clustering issues and crashing. As a result, it is critical that you upgrade to the latest available version, especially if you are using 19.4R2-S3 or below.
