jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger
writter faster that the logger is able to print this out to its out
stream. A very large collection of unwritten log outputs had been seen
during strong crawling. The new ArrayBlockingQueue is limited to prevent
this case.
- added log warnings in case that search processes run into time-out
situations
- better concurrency for Integer formatter (used a non-synchronized
formatter before)
- bugfix for search termination (a poison pill was missing)
- added timeout parameters for search (again) -> target is, that they
are never reached.
for example search for "passwd /ftp". This can also be done with /http /https and /smb
- fixed some search throttling processes that should protect your peer against search DoS or strong search load

"THREADS WITH STATES: LOCK FOR OTHERS"
will show only such threads that lock other threads. This is the 'opposite part' of the blocked threads.
Because that this uses a thread dump that is produced with a kill -3 on the PID of the process and such thread dumps are written by the Java core outside of System.out and Sytem.err it is necessary to read the dump from a log in the file system. Such a log is only written if YaCy is started with startYACY.sh on a linux system. That means:
this feature is only available on linux and Mac OS X if YaCy is started with ./startYACY.sh -l
