Firefox browser freezes up a lot
Have you ever had sex with a dead woman? Then you know what I mean. It's like you are trying to do something, waiting for it to respond but it just does not respond, ever...
This is what it feels like when using Firefox with many tabs opened. I don't mean too many, I mean like 5 or 6 tabs, especially if one tab was using flash player like maybe you were watching youtube in one tab.
I just keep restarting Firefox like 5 times a day or more, while I never have to restart the Chrome, I mean in days and even weeks, my Chrome is just open, many tabs are running, no problem.

Best source for Apache server discussion lists
Apache server foundation is home to many interesting open source projects, not just web server related. Some are frameworks, some are CMS, and many are Java related projects.
If you want to keep up with all the discussions about these projects, there is a superb web based archive for the Apache projects mailings lists and forums, here is the url:
apacheserver.net
Check it out.

SQL_BUFFER_RESULT may return stale result
Careful with SQL_BUFFER_RESULT in your mysql SELECT statement
While this may speed up the selects (sometimes by a lot), it will also get you the cached result, in some cases the result may be stale, not reflecting the changes that took place after the previous result was cached.
This was probably not intended to be like that, may be just a weird behavior when using PDO and somehow temporary table that was created for that BUFFER_RESULT was not removed. I don't know why, I am not a mysql developer, I just know what I see - when using SELECT HIGH_PRIORITY SQL_BUFFER_RESULT .... with php PDO class, the result may be stale.

Another day, another total lockup of MySQL, when it locks up, it locks up and stays locked like a dead cunt - forewer.

Looks like memcached was freezing Apache 2.2
Very bad idea to have both php extensions - memcache and memcached to be loaded at the same time.
I think this was causing the unexplained freezing of Apache 2.2
It was very difficult to track down the cause of Apache just freezing - no timeout error, no errors at all, just sitting there waiting forever for page to load.
After trying everything else, I decided to comment out loading memcached php extension and only load and use the good old reliable memcache extension.
Some tests claim that memcached is faster than memcache, but the difference is basically in single milliseconds, like who cares.... Not important when you usually saving couple of seconds worth of complex sql selects (some long sql selects that have several LEFT JOINS sometimes take 15 seconds when mysql has to create temporary table).
Anyway, I don't know if the problem was that some of the sites on the server were using memcache and some were using memcached, so I needed to load both extensions in php.ini
After ditching the memcached and only using memcache, the problems with Apache seemed to go away. Keeping my fingers crossed, so far so good.
