+ gftp crashes every few hours 'cause ("OutOfMemoryError" using both OpenJDK and Sun JDK). The issue has been solved upgrading java JDK 1.6 package.
+ Increased the number of movers in order to reduce pending transfers.
+ CREAM2 upgraded (glite-CREAM moved from 3.2.13-1 to 3.2.14-1.sl5, glite-SGE_utils.x86_64 3.2.3-1.sl5
+ Security fix on Apel service
+ LFC failures due to "Bad magic number": hanging gpfs connections causing lfc timeouts. The work around was to change CREAM config to decrease gpfs load.
