----------------------------------
Summary: Parsing some XLS documents hangs entire JVM, requires
kill -9
Key: TIKA-1132
URL: https://issues.apache.org/jira/browse/TIKA-1132
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.3, 1.2
Environment: Linux Suse:
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)
OSX 10.8.3:
java version "1.7.0_06"
Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)
Reporter: Ryan Krueger
Fix For: 1.1
Some XLS documents hang the entire JVM. A control-C or regular kill won't stop
the JVM, a kill -9 is required.
We're running within an email server application parsing documents to extract
text of all attachments. When we hit a message with the affected attachment
the entire JVM hangs and we mark the message to skip extracting the text from
the affected message the next attempt. Unfortunately, it kills all email
processing on the server until the internal watchdogs kill -9 the application.
We have seen the issue for several months with different documents, but they
are always Excel files. Some get complaints from Excel when opening but not
all.
In addition to experiencing the problem on our Linux servers I have tested on
OSX and experienced the same problems. I ran the Tika UI and select the
affected file or run the CLI. The problem is the same.
Tested with java -jar /path/to/tika-app-1.3.jar -t /path/to/file.xls
When running on multi-CPU machines there are two threads running at 100% every
time.
Unfortunately, so far I am unable to post any affected documents publicly due
to privacy concerns, however, I can provide samples privately for testing.
I have tested with 1.2 and 1.3 with the same result. Running 1.1 the text is
accurately extracted.
