I have noticed something extremely baffling. We use the get() function of LWP::Simple within mod_perl scripts, and it seems for long running servers, it gets slower and slower.
I have two servers here that would consistently take 8 seconds to process a get() call, when getting the same URL using the "GET" command would take about a second (very fast remote server). And the extra 8 second would show up for pretty much any URL regardless of the script. The really baffling part is that doing a soft restart of apache (apachectl restart) did not take care of the problem, but doing a hard restart (apachectl stop && apachectl start) will make the performance go back to normal. I don't know how long a server has to run in order for this issue to surface, it might be months, since we only noticed this lately and we don't typically hard restart production servers on a regular basis. Anybody else noticed something like this? -Mathieu
