Connection pool is fully used error

Hello,

after some time creating and editing documents in Nuxeo 7.2, I get this error:

No ManagedConnections available within configured blocking timeout ( 100 [ms] ) for pool org.apache.geronimo.connector.outbound.SinglePoolMatchAllConnectionInterceptor@19397d12

I tried increasing nuxeo.vcs.blocking-timeout-millis and nuxeo.vcs.max-pool-size, but after a while, I get the same error.

I've tried searching how can I fix this and why it happens, but with no results. Can someone explain me why it happens and how can I solve the problem?

I am facing the same issue. Did anybody encountered and got solution?

Nuxeo 7.2 is obsolete and unsupported. Please use Nuxeo LTS 2015 (7.10).
03/31/2016
fast_narcis
Using the LTS, doesn't fix the problem. It just means that it's supported and maybe somebody will look into it.

I'm having the same problem with Nuxeo 7.10. As said above the respective parameters show no effect
07/11/2016
Florent Guillaume
It means that there's a lot of work going on in the server and that all its threads are busy. You should use jstack to find out what's going on.
07/12/2016
René
I'm quite sure that 2 concurrent users of which one is browsing and the other is uploading a dozen files is not considered "a lot of work going on". It's a test server and therefore I can assure that there is no heavy traffic. Still the problem occurs quite often. After server restart it is gone and when working with the server for a few minutes, then the error occurs, especially when uploading multiple files at once via drag&drop. Multiple files means here 10-15 with an overall size of <20 MB.
07/12/2016
Florent Guillaume
As you can imagine we have plenty of customers using 2 concurrent users not having this problem. So you must debug on your side to give us an idea of what is going on. To start with this the first tool is jstack.
07/12/2016
René
I've uploaded the jstack output and the server log to dropbox for everyone to read: https://www.dropbox.com/sh/afz5lccr3z2k2th/AADM21POyQmI_K5wRHhaVXr5a?dl=0

Florent Guillaume
A fix was recently pushed (https://jira.nuxeo.com/browse/NXP-20113), it may help your case.
07/25/2016
René
I cannot confirm it finally, since the bug was not always there from the beginning and sometimes appeared only later, but from our first tests it seems that Hotfix 13 really fixed our issue. It is very interesting that there are so many customers not having the issue, since it doesn't seem to be our special configuration but a general Nuxeo problem that causes the error. Nevertheless: thanks for the help. Much appreciated.

hello ,I am getting same error as above in Nuxeo FT 8.2 Version,i am uploading document in nuxeo using document service and and retrieving through the NXQL query and it is working fine, but after some time i got the connection pool error and after restarting a nuxeo all operations are working. So is there any solution related to this problem? Is this possible to allow all connection in nuxeo?

just hit this one with nuxeo v10.10, says:

NuxeoException: Connection pool is fully used, consider increasing nuxeo.vcs.blocking-timeout-mill
is (currently 100) or nuxeo.vcs.max-pool-size (currently 20)

but netstat says there're only 8 established connections, so how can the pool be fully used?

It is possible that there is set to 8 a database parameter like for instance is "max_connections" in postgres.
