Hi,

in testing upgrade to hibernate search 4 we've come across a problem with deleted segment files never being closed.
We have increased open files limits to 10240 and still our tests don't complete. Eventually it keeps several thousand files open - all of which are marked as deleted when checking with lsof.
The only access type which doesn't suffer from this problem is mmap.
Here are the parameters we're using:

<prop key="hibernate.search.default.directory_provider">filesystem</prop>
<prop key="hibernate.search.default.indexBase">/tmp/test</prop>
<prop key="hibernate.search.default.filesystem_access_type">nio</prop>
<prop key="hibernate.search.default.locking_strategy">single</prop>
<prop key="hibernate.search.default.exclusive_index_use">true</prop>

Has anybody else come across something like this? I have tried googling this but have found nothing so far...

Thanks, best regards,
Bostjan

Hi,

I must clearly be doing something wrong since nobody else has this issue in version 4 and above.
But I just can't figure out what.
I have even created a jira issue with a small test case to demonstrate the problem - HSEARCH-1090.

Bostjan
