Core dump files found for Juniper

Vendor

Juniper

Description

A core dump is created when a process crashes. Indeni will alert when a core dump file is created.

Remediation Steps

The list of core dumps is retrieved by logging into the shell over SSH and retrieving the details of files found in /var/log/dump/usermode/, /var/tmp/*core* or /var/crash. Investigate the core dump files. If the issue is not clear, open up a case with vendor support and send them the file.

1. Run "show system core-dumps" command to locate system core files. The core dump files usually are located in "/var/log/dump/usermode/", "/var/tmp/*core*" or "/var/crash" directories.

2. Check for core-dumps that were created at to the time of failover.

3. If there is a core-dump created at the time of failover, consider uploading the file to the Juniper Networks Technical Assistance Center (JTAC) FTP server for further analysis and opening a case with the JTAC.

4. Review the following articles on Juniper TechLibrary for more information: Syslog message: Core dumped
