Description

Let me start by saying that I looked at MRM-1097 but it seems to be a different problem because there they say that the accumulating file descriptors were sockets and here they are index files.

Being more specific, our Archiva is accumulating several open file descriptors to already deleted files. In less than one hour it can accumulate as much as 1000 such file descriptors, quickly reaching the process file descriptor limit which we already increaded from 4K to 12K in an attempt to delay the problem.

This are the kind of descriptors I'm talking about:

we're due to review the use of the indexer in the next release, so hopefully we can pick this up at the time.

Do you have some data on how many artifacts you are processing through the indexer and how often?

I'm attaching the scan.log.gz file which was extracted from the archiva logs with this command:

grep -A16 'Repository Dir ' archiva.log >scan.log

In it you can see how many times the scan process was performed in the last days.

I'm attaching archiva-dsso.csv.gz. It contains a record of the number of those strange open file descriptors that I captured each 10 minutes since yesterday.

This problem looks like this http://www.mail-archive.com/java-user@lucene.apache.org/msg29216.html.

I'll try to upgrade only lucene's jar to an early version.

in the end I think we identified that the other problem was also related to the indexing, which should be fixed
