 Description   

I experienced the issue upgrading from 1.4.1 to 1.4.2 using https://downloads.mariadb.com/files/MaxScale/1.4.2/debian/dists/jessie/main/binary-amd64/maxscale-1.4.2-1.debian.jessie.x86_64.deb

Downgraded back to 1.4.1 and Maxscale starts without any issue.

My stacktrace is different than MXS-698 so I created a new bug.

Thank you for reporting.

Yes, there is an issue with 1.4.2 that manifests itself as a crash at startup.
We have fixed that and are currently working on 1.4.3 release.

Thanks, I missed the MXS-700 bug as it was already marked as closed.

osteenbergen Please try this again with the 1.4.3 release of MaxScale: https://downloads.mariadb.com/files/MaxScale

I can confirm that 1.4.3 is working as expected.
