When triggered via xinetd or ssh, the agents for AIX, FreeBSD, Linux, OpenWRT and Solaris were not able to execute asynchronous plugins and local checks in the background. Instead, the agents kept on running until the supposedly asynchronous tasks were completed or a timeout or occured. In the latter case, the following error message was displayed by the Check_MK services of affected hosts:

MKTimeout('Fetcher for host ... timed out after 60 seconds')
