Configuring Number Threads
I have this error message from the logs of Zimbra email running on SUSE 11.2

Is the thread maximum of 20 an operating system parameter, or is it part of the application code, or part of the java run time?
Part two, how would I increase that number?

mh_linkjar
MAVEN(1) User Commands MAVEN(1)
NAME
Maven - Creates a link in /usr/share/maven-repo for an existing jar.
SYNOPSIS
mh_linkjar [option]... [pom] [dest_jar] [link]...
DESCRIPTION
Create symlinks for a jar installed by other means. The symlinks created include links to the jar in /usr/share/maven-repo, at the correct
location for Maven. It can also create additional links to the jar, usually located in /usr/share/java.
Where
[pom] is the location of the POM associated with the jar to install.
GroupId, artifactId and version will be extracted from this file.
[dest_jar] is the path of the installed jar, usually located in the
usr/share/java folder.
[link] is an additional link to the jar to install, usually there should
be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging guidelines. Note that
there is no need to specify those particular links if the --java-lib option is used.
OPTIONS
-h --help: show this text
-V --version: show the version
-p<package> --package=<package>: name of the Debian package which
will contain this jar file
-e<version>, --set-version=<version>: set the version for the jar,
do not use the version declared in the POM file.
-r<rules> --rules=<rules>: path to the file containing the
rules to apply when cleaning the POM. Optional, the default location is debian/maven.rules Maven rules are used here to extract the
groupId, artifactId and version from the POM file.
-l --java-lib: Optional, if given it will install the jar into
/usr/share/java to comply with the Debian Java specification. The jar will be installed as /usr/share/java/$name-$version.jar and a
versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo
-n<name> --usj-name=<name>: Optional, the name to use when installing the
library in /usr/share/java when --java-lib is used. Defaults to the artifact id found in the POM.
-j<version> --usj-version=<version>: Optional, the version to use when
installing the library in /usr/share/java when --java-lib is used. Defaults to the version found in the POM.
-s --no-usj-versionless: Optional, don't install the versionless link
in /usr/share/java. This flag is used only when the -l or --java-lib option is given.
-c<classifier> --classifier=<classifier>: Optional, the classifier for
the jar. Empty by default.
-v --verbose: show more information while running
-n --no-act: don't actually do anything, just print the results
--skip-clean-pom: don't clean the pom, assume that a previous action ran
mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar
