xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext())

Hi, I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/users@xwiki.org/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case: ... xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ... but this of course doesn't solve the problem behind. -Pete -----Alkuperäinen viesti----- Lähettäjä:

Hello, My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs. Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these: ... java.bin  10095     tomcat  666r      REG      104,1  60931511   15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin  10095     tomcat  667r      REG      104,1  60931507   15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin  10095     tomcat  668r      REG      104,1  60931507   15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ? And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

Hello, My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs. Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these: ... java.bin  10095     tomcat  666r      REG      104,1  60931511   15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin  10095     tomcat  667r      REG      104,1  60931507   15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin  10095     tomcat  668r      REG      104,1  60931507   15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ? And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?
