Hi,we were also effected from the update 5.7.3+dfsg-1.7+deb9u2 causing lots of broken icinga checks.
Our workaround is pinning 5.7.3+dfsg-1.7+deb9u1.What's unclear from the solution if 5.8 also will be available in stretch and buster which we need. Otherwise it would be great to enable extend in 5.7.3 for those versions.
