Hi all,

we get exceptions during stress tests from Lucene. The environment is the following:

We have set up a master/slave configuration as described in the documentation. Typically, we test with two glassfish nodes that copy the index from a shared directory. But, the problem occurs also if we use only one slave node that copies the index from the local disc. For testing we use a low refresh period of 20 seconds. If we increase the period to several minutes then the problem does not occur any longer. However, we don't know if we just did not have enough chances to run into the problem. OS: Windows, file handles: default, Hibernate Search 3.1.1, Lucene: 2.4.1. Thanks in advance.

Best regards,

Christoph

Hi Christoph,
Both Search 3.1.1 and Lucene 2.4 are rather old, and from that time we fixed several issues in the area. I believe the problem you're having is that the SharingBufferReaderProvider should not be used with the switching directories: it might be "sharing a buffer" with the wrong Directory instance. If you can't upgrade to latest, I'd advise to try using the not-shared Reader strategy : http://docs.jboss.org/hibernate/search/3.1/reference/en/html_single/#d0e669

Hi Sanne,

thanks for the quick response.

1. Hibernate upgrade
We tried to upgrade Hibernate and Lucene to the next version, but had compile errors in the workspace. For the current version that is about to be released it seems too late. But for the next release we are allready porting the product to later JEE and Hibernate versions.

2. not-shared Reader strategy
We have tried already hibernate.search.reader.strategy = not-shared. But the result was mostly the same.

The documentation mentions that the refresh period should be longer than the copy time. We have not measured the copy time during load test. But the index is only a few KB. We wondered if a too short refresh time could cause this problem.

We test only on Windows, because this is the given production environment. Is the master/slave configuration working on other environments e.g. Linux?


Best regards,

Christoph

Right, we try hard to keep backwards compatibility but we take the liberty to cleanup things in mayor releases; this should be useful:
https://community.jboss.org/wiki/HibernateSearchMigrationGuide


A few KB index should take very short to copy so that's unlikely. Could you send a full stack like the one you posted but using the non-shared configuration?
Might be useful also to check the changelogs in JIRA to explore the long list of fixes since your version.

https://hibernate.onjira.com/browse/HSEARCH#selectedTab=com.atlassian.jira.plugin.system.project%3Achangelog-panel


Yes that should work on Windows too, we have Jenkins machines on several OSs and database combinations (windows included).

Ok, thanks for the support. We have not kept the results for the non shared configuration. We have to rerun the tests. I will post more stack traces next week.

Best regards,

Christoph

The problem seems to be the same as:

However, we get such kind of problems also without NFS, even if we use only a single slave a store the shared index on a local disk.
