[SR-Users] pcscf - removing registration entries from hash table

[Daniel Ciprus]

Hello,

Our current setup is Kamailio as IMS core and we're observing following behavior:

Clients register themselves over TCP so pcscf creates hash table which keeps these information in memory. Once tcp reset occurs for any reason, registration entry stays in the memory and client re-registers himself with new pair ip:port. This kind of behavior creates problem because outbound SIP messages are being forked and requests are sent to non-existent tcp sessions which creates a lot of timeouts and confusion for AS.
We're using ims_usrloc_pcscf module to keep reg entries in and as I noticed, with usrloc module, there was an option which automatically removed entry from hash table once tcp session was closed which is not the case in this module.

Any suggestions how to get out of this ?

thanks for any hints/suggestions.
