Hi--
I'm relatively new to Lucene. When I run my app, I get a JVM error.
This gets called a lot, but only fails every once in awhile (maybe 1 in
100 calls?)
I filed a report with Sun, but I don't expect to hear anything from them.
So, I was wondering if any Lucene experts have run across this or have any
ideas for workarounds (if not, I'll have to take lucene out of my system
and manage the termvectors myself):
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# SIGSEGV (0xb) at pc=0x0000002a95a5c300, pid=26545, tid=1085655392
#
# Java VM: Java HotSpot(TM) 64-Bit Server VM (1.5.0_06-b05 mixed mode)
# Problematic frame:
# V [libjvm.so+0x4fa300]
#
# An error report file with more information is saved as
hs_err_pid26545.log
That error file is huge, but the salient part seems to be:
Stack: [0x0000000040a5c000,0x0000000040b5d000), sp=0x0000000040b59f70,

Current CompileTask:
opto:1621
org.apache.lucene.index.IndexReader$1.doBody()Ljava/lang/Object;
(99 bytes)
My code that is causing the JVM crash is:
//Get the terms and frequencies
IndexReader indexreader = null;
TermFreqVector tv = null;
try {
indexreader = indexManager.getIndexReader();
tv = indexManager.getTermVector(indexreader, item);
if(null==tv) {
if(log.isErrorEnabled()) log.error("No term vector for item " +
item.getId());
//??? better handling
return;
}
}
finally {
//XXX should close earlier
if(null!=indexreader) {
try {
indexreader.close();
}
catch(IOException ex) {
if(log.isDebugEnabled()) log.debug("IOException cleaning up
indexreader ", ex);
}
}
}
//Replace the String[] with its equivalent long[]... (and tally up
total occurs)
String[] termstrings = tv.getTerms();
int[] freqs = tv.getTermFrequencies();
Thank you for your help,
Dan
