<p class="MsoNormal">Hi, all!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a rather murky situation. A colleague accidentally completely removed the Xymon (4.3.3 / Solaris) server home directory recently. It was restored from backups, but since then that server has not been completely functioning. (‘Don’t
know if our symptoms are related to the home dir “zap” or what…)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We periodically run the ghostlist.cgi app from cron and now these instances sometimes don’t exit. When I run truss on them, I see they are almost continuously calling brk(): allocating anonymous memory for that instance’s heap. It’s gotten
so bad that we’ve had this server’s resources completely depleted and now have had to turn off the cron jobs<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The xymond daemon is no longer accepting connections, despite the fact that this server has been stable for years.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> The system was rebooted last night and seemed to be functioning throughout the night but stopped updating around 7:30 AM<o:p></o:p></p>
