Lewis John McGibbney resolved NUTCH-314.
----------------------------------------
Resolution: Won't Fix
close of legacy issue
> Multiple language identifier instances
> --------------------------------------
>
> Key: NUTCH-314
> URL: https://issues.apache.org/jira/browse/NUTCH-314
> Project: Nutch
> Issue Type: Bug
> Affects Versions: 0.8
> Environment: OS: Linux RHEL 4
> JDK: 1.5_07
> Reporter: Enrico Triolo
>
> In my application I often need to perform the inject -> generate -> .. ->
> index loop multiple times, since users can 'suggest' new web pages to be
> crawled and indexed.
> I also need to enable the language identifier plugin.
> Everything seems to work correctly, but after some time I get an
> OutOfMemoryException. Actually the time isn't important, since I noticed that
> the problem arises when the user submits many urls (~100). As I said, for
> each submitted url a new loop is performed (similar to the one in the
> Crawl.main method).
> Using a profiler (specifically, netbeans profiler) I found out that for each
> submitted url a new LanguageIdentifier instance is created, and never
> released. With the memory inspector tool I can see as many instances of
> LanguageIdentifier and NGramProfile$NGramEntry as the number of fetched
> pages, each of them occupying about 180kb. Forcing garbage collection doesn't
> release much memory.
> Maybe we should cache its instance in the conf as we do for many others
> objects in Nutch.
