>Description:
Hello,

There are strange things start to happend since two weeks already, i.e.:
-- During just a bit Server load Apache output giving out garbled(half rendered) images and web page layout also with strange header content symbols substituted blah-blah-blah...
-------------------------------------
Installed: Web server	Apache/2.2.13 (FreeBSD) DAV/2 PHP/5.2.11 mod_ssl/2.2.13 OpenSSL/0.9.8l
Hardware: AMD Dual-Core+5600, 4GbRAM, 2x400Gb HDD:
-- /usr at one full HDD, and the rest OS data at the another HDD.
----------------------------------
The problems with garbling goes away when I reboot the server and goes back on when amount of RAM available getting smaller.
