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.

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?
