Subject [jira] Commented: (CAMEL-1771) ProducerCache should be limited to not eat memory (was: recipientList leaks memory)
Date Tue, 30 Jun 2009 06:30:07 GMT

Andres commented on CAMEL-1771:
-------------------------------

Another thing I was wonderingi is that do we realy need ProducerCache in RecipientList ? Path
to the camelContext seems relatively short  (allmost direct call to camelContext.getEndpoint(uri)
) and camelContext caches endpoints anyway

> I found that RecipientList leaks memory .
> The problem is that RecipientList stores endpoints in producerCache and cache key computed
by using getEndpointUri. If endpoint uris are unique ( as we have ) then every new entry will
stored in cache and will never released.
> In example we are using recipientList  to send messages to the external http server,
every url contains unique query parameters therefor every recipientList entry will create
new producer ant that producer will stored in producerCache.
> In our system recipientList wlil leak about 20M per day
> Unfortunately I was unable to find any workaround
