and
-XX:ReservedCodeCacheSize=1024m
after appearance of a malloc error together with a crash of the jvm which stated at the end of the log:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32756 bytes for ChunkPool::allocate
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
this follows the last two points in the list of recommendations. To set appropriate values the default values from

the new replacement is taken from http://xerces.apache.org and has the version 2.11.0 and was inside the file Xerces-J-bin.2.11.0.tar.gz
and consists of two files named xercesImpl.jar and xml-apis.jar
The original purpose of that library was to support:
- content parsers
- optional seed uploader
- SOAP API (which will be committed later)
Since the SOAP API does not exist any more the purpose is to support content parser and an optional seed uploader

YaCy supports now the storage to remote solr indexes.
More federated storage (and search) methods may follow.
The remote index scheme is the same as produced by the SolrCell; see
http://wiki.apache.org/solr/ExtractingRequestHandler
Because this default scheme is used, the default example scheme can be used as solr configuration
This is also the same scheme that solr uses if documents are imported with apache tika.
federated solr storage is switched off by default.
To use this, do the following:
- set federated.service.solr.indexing.enabled = true
- download solr from http://www.apache.org/dyn/closer.cgi/lucene/solr/
- extract the solr (3.1) package, 'cd example' and start solr with 'java -jar start.jar'
- start yacy and then start a crawler. The crawler will fill both, YaCy and solr indexes.
- to check whats in solr after indexing, open http://localhost:8983/solr/admin/
Until now it is not possible to use the solr index to search with YaCy in that solr index.
This functionality is now available for two reasons:
1) to compare the functionality of Solr and YaCy and to compare the search speed
2) to use YaCy as a search appliance for people who need a crawler or other source harvesting methods
that YaCy provides (like dublin core reading, wikimedia dump reading, rss feed reader etc) if people still
want to use solr instead of YaCy.

- remove the library
- added two classes from the httpclient-3.1 library as source code to YaCy because these classes were used by the YaCy HTTP Server
- modified the added classes ChunkedInputStream and ContentLengthInputStream in such a way that:
* there are no more dependencies to httpclient-3.1
* these classes had been simplified to serve only the purpose for the YaCy httpd

- added some clear statements that shall clear static cache size within the pdfbox library
- the pdfbox library contains a memory leak; it is unsafe to run a peer with pdf parser permanently on.

the home path can now be distinguished between
- data home; the path where the DATA directory is created
- application home; everything else
This will make it possible to store application data on Mac releases within the
~/Library/YaCy
directory; a place where Mac applications write their data.
Similar techniques will be possible for debian and windows.
To use the new data path, YaCy can be started with
-start <data path>
or
-gui <data path>

You can now create a YaCy Mac application like this:
- build a new version of YaCy
- take everything that is in the yacy home directory (from the fresh build) and move it into a copy of the YaCy.app directory under YaCy.app/Contents/Resources/Java/
- ready: double-click the YaCy.app icon and the new YaCy gui starts, then the browsers is also opened.
- if the Mac application is terminated, also the YaCy demon should be stopped automatically and vice versa. This is currently not really good working and needs some more care.
A build script for this is missing. Does anyone know how to do that in ant?
