A tweak here and a tweak there
Posted by Ian Holsman
So.. people at work have been complaining about one my monitoring servers continually freaking out, and being slow..
so I thought.. why not open up a 2nd port with just mod-perl replacing some dodgy CGIs, freeing up some connections on the original port making it snappier at the same time.. win-win.
This is what I wake up to ;(.
The machine has gone beserk. for some reason a ‘stable’ perl program running via peristent perl had none of these issues, change it to mod-perl .. and wow less than 24 hours before I need to bounce.
now.. If I didn’t have procallator running on the box I would still be puling my hair out trying to figure what was going on.. at least now I have a clue on what the problem looks like before the machine hangs.
I’m still not 100% confident that it is directly related to my change.. now that the ‘display’ server is faster, it got hammered harder by other things ;( I’m sure this will provide a weeks of hair pulling.
oh.. all the perl code does is write a file to disk, and it’s been running for years..so it is an interaction somewhere.
