check_dns exits with an error when executed by mod-gearman workers #176

Closed topinet closed 5 months ago

topinet commented 5 months ago

When check_dns is executed by a mod-gearman worker it fails, because nslookup exits with an libuv assertion:

nslookup: ./src/unix/core.c:602: uv__close: Assertion `fd > STDERR_FILENO' failed.

This seems to be caused because nslookup can't use STDERR when executed by a mod-gearman worker.

As a result check output is "DNS CRITICAL - '/usr/bin/nslookup -sil' msg parsing exited with no address"

I also check that check_dns doesn't fail when executed locally (using localservicegroups in module configuration)

Could you try the new worker from https://github.com/ConSol-Monitoring/mod-gearman-worker-go This old c worker will soon be removed in favor of that go worker anyway.
