Re: Disappearing tasks and OOMex.

Hi James, there were problems in the past where failed tasks would be removed from config. This has been fixed in a newer release (currently 1.3.4 is available).

The OOM exception is a bit more concerning, haven't seen this particular issue in the past, although if you have a large number of repositories, our NFC (not found cache) can get rather large, and consume a large amount of memory. This is being reworked for 1.4.0 to use a single cache (rather than a cache per repository) to help ease that unbounded memory usage. Also, in 1.3.5 (release due out shortly) the default caching will be configured to hold a smaller number of records, which has helped out public server (repository.sonatype.org) quite a bit.

Hi all,

Using nexus 1.3.1.1,

    CentOS 5.2

    Sun java version "1.6.0_07"
        Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
        Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

I've come across an issue with scheduled tasks disappearing which has happened on a number of occasions now...

Most recently nightly re-index disappeared from the tasks view. There was nothing worthy in the logs (as I only just noticed the task was missing) but the system rss feed shows the following after which it appears the task never runs again and is probably lost..

(note even though we have an OOMEx nexus is still serving requests :-) )
