Although i'm not an expert on the *exact* details of the
ML update process i'd guess the following: Up to the re-
boot some old libs (probably from the original 4.3.3 OS
level) were in use by apache/tomcat. On disk they were
already replaced with those supplied by the update. By
rebooting you forced apache/tomcat to use the new libs
from disk. Now it will not run since those new libs seem
not to be compatible with the 4.3.3 libs.
A solution would be to use a newer apache/tomcat version
from the linux toolbox. If you are bound to a specific
version of apache/tomcat by your application you might
have to build that particular apache/tomcat version your-
self, using the new libs from 5.2ML7.
