Rob Tulloh closed TIKA-933.
---------------------------
Resolution: Duplicate
Web server stopped responding. Duplicate of TIKA-934
> Tika in server mode stops responding and reports NPE over and over in logs
> --------------------------------------------------------------------------
>
> Key: TIKA-933
> URL: https://issues.apache.org/jira/browse/TIKA-933
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.1
> Environment: CentOS 5.x
> Reporter: Rob Tulloh
> Priority: Critical
>
> We run tika in server mode via:
> /usr/java/jdk/bin/java -Dlog4j.app.name=-server
> -Djavax.xml.soap.MessageFactory=com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl
> -Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true -server -Xms256M
> -Xmx768M -XX:+HeapDumpOnOutOfMemoryError
> -XX:HeapDumpPath=/var/log/oom/content-extractor-8983.dump.1 -server -Xms500M
> -Xmx500M -jar /opt/ems/ces/tika-app-1.1.jar --text --encoding=UTF-8 --server
> 8983
> Our client talks to this over port 8983. We pass data via the socket and get
> the responses back. However, sometimes, tika will get into a bad state and
> stop responding. When this happens, we see this in the logs:

> We have tried to figure out what causes this with no success. We only know
> that once the server gets into this state, there is no recourse but to
> restart the tika service.
