[SR-Users] Kamailio stability/timing problem w.r.t. registrations?

[Daniel-Constantin Mierla]

Hello,

can you add an xlog() at the start of the main route block and log a 
message for any request received? Keep the debug level low. It should 
show if the sip request gets to application level, it may happen to be 
dropped from the network interface or kernel.

You can put another xlog before the save() function to see if 
registration requests are getting there. I am not familiar with ser 
flavour of registrar and usrloc modules. You can switch to kamailio 
flavour modules and see if reproduces. I haven't seen such issues with k 
flavour.

Cheers,
Daniel
