<div style="font-family: Calibri, sans-serif; font-size: 14px; "><br>

<div style="font-family: Calibri, sans-serif; font-size: 14px; ">Yesterday, I was working to clean up email alerts coming to teams from our server.</div>
<div style="font-family: Calibri, sans-serif; font-size: 14px; ">I modified the alerts.cfg file</div>
<div style="font-family: Calibri, sans-serif; font-size: 14px; ">Added a Macro definition = MAC_SRMDK = script/home/xymon/server/ext/html_mail.pl myemail@company.com FORMAT=TEXT</div>

<div style="font-family: Calibri, sans-serif; font-size: 14px; ">After doing this, and some other changes, I went to the xymon pages and clicked the Info button but then started getting a msg like this:</div>

<div>[Tue Aug 07 13:35:19 2012] [error] [client 1.1.x.x] Premature end of script headers: svcstatus.sh, referer: http://xymonserver.company.com/xymon/#servername</div>
<div><br>
</div>
<div>When trying to run the xymond_alert —test hostname cpu</div>
<div><br>
</div>
<div>This returned: "Segmentation fault"</div>
<div><br>
</div>
<div>It turned out that among my changes to alerts.cfg, I left the space " " from between mac_srmdk=script and home/xymon….</div>
<div>So the missing space was causing all this grief and I didn't catch it till I took a long look at the file.</div>
<div><br>
</div>
<div>Once I put the " " space between the =script /home/xymon…</div>
<div>And the script file, it cleared all the errors up.</div>
<div>It may be obvious to others, but I was surprised to see a lot of posts in my google searches about these messages, so I thought I would share just in case it happens to anyone else and they can trace it to a simple typo on the cfg file.</div>
