Resolved Issues


This section lists the issues that have been fixed in the Junos OS Release 18.3R3.

For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.

Flow-Based and Packet-Based Processing

  • With vSRX3.0, REST API query returns a 500 error. This is due to the incorrect mapping of the path to the required REST API libraries. PR1412087

  • If larger data types are written into smaller data types, the neighbor stack pointers are overwritten, thereby corrupting the data types. Accessing the address generates a core file, and the vSRX instance stops functioning. PR1412441

  • With vSRX instances, REST API query returns a 500 error. This is due to the incorrect mapping of the path to the required REST API libraries. PR1426588

Platform and Infrastructure

  • On vSRX 3.0 instances, the pkid process might generate core files when the auto-enrollment feature is enabledPR1415968

  • On vSRX instances, when the secure wire feature is used, a flowd process core file might be generated when one of the secure wire interfaces goes down. PR1430071

  • vSRX instances on Microsoft Azure cannot be managed using the serial console. PR1439148

  • If downloading dynamic-address feed from HTTPs server that is configured on security director is available, then the download process fails. This issue causes the IP address contained in the list not be sent from SD to the platform. If the platform has policy referencing the IP address, then that will not match passing-through traffic. PR1442248

Routing Policy and Firewall Filters

  • If one domain address is configured inside policies, then the device or the instance assumes that this domain address is needed by policies and will always retry to get the addresses for this domain. This domain will remain in the "DNS cache" until it is removed from all policies. When DNS server replies with any error codes (such as ServFail, NXDomain, YX Domain, and so on), the current DNS cache entry (domain name and ip-list) is not flushed. PR1426186

Unified Threat Management (UTM)

  • UTM WR might have memory leak with utmd process on RE. PR1445222


  • vSRX 3.0 supports suiteb-gcm-128 and suiteb-gcm-256 IKE and IPsec proposals. PR1400214

  • IPsec VPN traffic drop might be seen with NAT-T scenario. PR1444730
