Re: [webmin-l] webmincron.pl and rpm query problem

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

It may be just that the command only crashes occasionally or when the system
is under load, so Webmin's frequent runs trigger the crash. It is possible
to turn off this RPM status collection if you like, at Webmin -> Webmin
Configuration -> Background Status Collection.
