Bram Luyten (@mire) commented on DS-1458:
-----------------------------------------
Closed the previous pull request, created a new one that only increases the
default max connection value
https://github.com/DSpace/DSpace/pull/194
When looking into this more closely, I'm not sure if I like the
WHEN_EXHAUSTED_GROW because it would allow a memory leak to exist.
> Connection pool exhausted

> Key: DS-1458
> URL: https://jira.duraspace.org/browse/DS-1458
> Project: DSpace
> Issue Type: Bug
> Components: DSpace API
> Affects Versions: 1.7.2, 1.8.0, 1.8.1, 3.0
> Reporter: Bram Luyten (@mire)
> Attachments: postgres_connections_ALL-year.png
>
>
> This issue follows from a recent discussion on the mailing list:
> http://comments.gmane.org/gmane.comp.db.dspace.user/18148
> Peter Dietz reported that changing the behaviour of the connection pool,
> allowing automatic growth, fixed the errors for him:
> https://github.com/osulibraries/DSpaceOSUKB/commit/c627ebdb738efbf46ba7a338180099fa38b96a66.diff
> This still doesn't quite uncover if the connection pool is being managed full
> proof (e.g. are connections always properly returned or not?)
> Also, the default value of 30 for max connections in the default DSpace 3.0
> build properties might be too low to start with.
