Thanks. The message is stored again in failure route with m_store(), since we do not want that message will be lost. When user registers again, the message can be dumped. As i see when kamailio send the stored message with m_dump the record has disappeared from table. And in failure route the m_store put it into db again.

Hello,

the messages are stored only if m_store() is called, check your config and be sure you do not call it again for a message that was initiated from msilo.

Cheers,
Daniel

Hi,

 

I’m using kamailio’s silo module to store offline messages in it. I set extra_hdrs modparam to e.g. : ‘Resent-from-silo’ so the clients get information that the message has arrived directly (immediatelly) from the sender or it was stored offline and comes from silo.

So the problem is the following: 

  • if receiver’s socket is broken (e.g. airplane mode on mobile) and kamailio ‘thinks’ it is registered, server tries to send the message
  • message will be timed out and based on config it will be stored in silo.
  • the next step is to check if receiver is registered or not (since the client can re-register during 30sec until the message has timed out)
  • If client is registered, kamailio tries to send the message immediately with m_dump().
  • If the receiver’s connection is still broken, the message will be timed out and store in silo.
  • In every store, a new ‘resent’ extra_hdrs value is appended.

 

When extra_hdrs length reaches 1024 bytes, the m_dump will fail and it blocks the dumping of messages to the given receiver.

 

Question: can extra_hdrs value be removed before store? Or what can be the solution not to duplicate the extra_hdrs value in some bad network situation?

 

Peter
