perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

All,

A bugfix release of a few perfSONAR packages is now available. The updates include the following:

- The pcheduler packages were updated to version 1.0.2.5. They contain the following changes:

    - Improved handling of run execution under very heavy loads. Previously calls to select could exceed system limits causing runs to fail.

    - Improved diagnostics when restoring configuration and data

    - Attempt to put old data back in place if database load fails

    - The pscheduler systemd unit files set higher ulimits on CentOS 7 to help prevent too many open files/too many processes errors.

    - Allowed the Missed to Failed state transition

- The perfsonar-toolkit packages were updated to 4.0.2.3. They contain the following changes:

   - The perfsonar-toolkit-security package was updated to configure memcached to only listen on localhost. This provides an extra layer of protection if the host firewall is not running

   - perfsonar-configure_nic_parameters was updated to configure coalescing based on the NIC driver installed

   - Update reverse_traceroute.cgi to version 7.4

- Updates perfSONAR bundles to version 4.0.2.3. Contains update for apache systemd unit file to set higher ulimits on CentOS 7. This helps prevent too many open files/too many processes errors.

- OWAMP was updated to version 3.5.6. The systemd unit files set higher ulimits on CentOS 7 to help prevent too many open files/too many processes errors.

- iperf3 was updated to version 3.5

These packages should be available for all supported version of CentOS and Debian. If you have auto-updates enabled, you should get these updates automatically.

Thank you,

The perfSONAR development team
