When I try to ssh in after it's been running overnight, it's really sluggish and will even timeout before the connection can be made. This has happened twice, even after a mysql tune-up (reduced memory footprint).<br /><br /> Generally the load comes down if I stop the mysql process, but I still had to hit the hw reset button to get it back up to speed, as it would not seem to come back up after a sudo reboot command.<br /><br /> After that it appears to run fine through the day, with no discernible climb in load, cpu or swap use except in response to immediate demands.<br /><br /> Here's a top screen cap 1st thing this morning (after I'd already stopped mysql):<br /><img alt="" src="https://tehforum.co.uk/forum/get_attachment.php?webtag=DEFAULT&hash=8a7976f8c1211113c0576823215fd05b&filename=top-071216.gif" /><br /><br /> Also attached is a phpsysinfo screen cap after reboot, with sql running, showing it's pretty much 'normal' load while I'm here keeping an eye on it (I've not expanded running processes sections, as you can see they were consuming very few resources so I don't think that would be helpful).<br /><br /> Any ideas what may be causing this issue?<div class="edit_text">EDITED: 12 Jul 2016 17:26 by DSMITHHFX</div> </div> <div class="message_attachments"> <span>Attachments:</span> <ul> <li><span class="image attach"></span><a href="get_attachment.php?webtag=DEFAULT&hash=d742a6cc0721bf42518dd8237e1e222d&filename=phpsysinfo.gif" target="_blank">phpsysinfo.gif</a></li> <li><span class="image attach"></span><a href="get_attachment.php?webtag=DEFAULT&hash=8a7976f8c1211113c0576823215fd05b&filename=top-071216.gif" target="_blank">top-071216.gif</a></li> </ul> </div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=41778.1&return_msg=41778.1" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="41778.1"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a41778_2"></a><div class="message" id="message_41778_2"> <div class="message_header"> <div class="message_from"> From: CHYRON (DSMITHHFX)<span class="message_time">12 Jul 2016 20:31</span> <div class="clearer"></div> </div><div class="message_to">To: ALL<span class="message_count">2 of 15</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=41778.2">41778.2</a></div> <div class="message_body"> OK, so I gave it a swappiness haircut (60 --> 20), and an apache2 mpm_prefork haircut: <div class="quotetext"><strong>Code:</strong> </div> <pre class="code"> StartServers 3 MinSpareServers 3 MaxSpareServers 3 MaxRequestWorkers 50 MaxRequestsPerChild 750</pre> wordpress still works, though it's noticeably slower (though that could also be down to slow-ass tenfourfox)<br /><br /> Here's a late-afternoon top screencap.
