Jabber offline message caching

[aalejo]

Dear Community

Does someone knows for how long Presence servers keeps offline messages? 

Any way to configure offline message aging time? Any default value?

Since presence storage is limited i would believe there is a limit on number of messages and a maximum aging time for that message...

Thank you

Alex

IM and Presence Service limits offline messages to 100 per user up to a maximum of 30000 per node.

And the help for the parameter does mention the concern for space

Check this checkbox if you do not want the IM and Presence Service to store IMs that are sent to an offline contact and deliver those messages the next time the user signs in. In large deployments, this feature could require message storage space, so you may want to turn off (suppress) offline instant messages to increase performance. In enterprises with strict privacy policies, it may be required to suppress offline instant messaging and not store any offline messages on the IM and Presence Service while the user is offline.

Hey Jaime

Thank you for response :) but are those messages never age?. When those messages get deleted? Are they store on RAM or on HDD? Rebooting server delete those messages?

My question goes more on the aging time of those messages and for how long they will stay and where.

Thank Alex
