Mike,

with sofia loglevel all 9, I can see that sometimes (frequency hard to guess), during 4-5 secondes, FS writes those messages in the log for each REGISTER or OPTIONS request:

nta.c:3012 agent_recv_request() nta: OPTIONS (102) going to existing OPTIONS transaction
nta.c:3012 agent_recv_request() nta: REGISTER (116849) going to existing REGISTER transaction

It’s like it considers it’s already dealing with a such request (which it never replied to).

A typical regular flow of logs for a REGISTER which was responded to is:

nta.c:3085 agent_recv_request() nta: REGISTER (108692) going to a default leg
nua_server.c:102 nua_stack_process_request() nua: nua_stack_process_request: entering
nua_stack.c:899 nh_create() nua: nh_create: entering
nua_common.c:108 nh_create_handle() nua: nh_create_handle: entering
nua_params.c:480 nua_stack_set_params() nua: nua_stack_set_params: entering
soa.c:280 soa_clone() soa_clone(static::0x7fda40001930, 0x7fda40001130, 0x7fda40039330) called
soa.c:403 soa_set_params() soa_set_params(static::0x7fda40207f40, ...) called
nua_stack.c:271 nua_stack_event() nua(0x7fda40039330): event i_register 100 Trying
nua_stack.c:359 nua_application_event() nua: nua_application_event: entering
nua.c:366 nua_handle_magic() nua: nua_handle_magic: entering
nua.c:879 nua_respond() nua: nua_respond: entering
nua_stack.c:529 nua_signal() nua(0x7fda40039330): sent signal r_respond
nua.c:921 nua_handle_destroy() nua: nua_handle_destroy: entering
nua_stack.c:529 nua_signal() nua(0x7fda40039330): sent signal r_destroy
nua.c:366 nua_handle_magic() nua: nua_handle_magic: entering
nua.c:921 nua_handle_destroy() nua: nua_handle_destroy: entering
nua_stack.c:573 nua_stack_signal() nua(0x7fda40039330): recv signal r_respond 200 OK

When it fails to respond, it is:

nta.c:3085 agent_recv_request() nta: REGISTER (108693) going to a default leg
nua_server.c:102 nua_stack_process_request() nua: nua_stack_process_request: entering
nua_stack.c:899 nh_create() nua: nh_create: entering
nua_common.c:108 nh_create_handle() nua: nh_create_handle: entering
nua_params.c:480 nua_stack_set_params() nua: nua_stack_set_params: entering
soa.c:280 soa_clone() soa_clone(static::0x7fda40001930, 0x7fda40001130, 0x7fda402dc590) called
soa.c:403 soa_set_params() soa_set_params(static::0x7fda4014f880, ...) called
nua_stack.c:271 nua_stack_event() nua(0x7fda402dc590): event i_register 100 Trying
nua_stack.c:359 nua_application_event() nua: nua_application_event: entering

It’s difficult to know which lines are related in the log, but when FS does not answer the 200 OK, I am definitely missing a line like:

nua_stack.c:529 nua_signal() nua(0x7fda40039330): sent signal r_respond

you can try sofia loglevel all 9

see if that tells you anything when we get one we don't respond to...  also get latest 1.6 and see if that helps

All,

I noticed recently that sometimes FS (1.6.6) does not honor REGISTER or OPTIONS requests coming from some customers.
Those customers register every 30 seconds, and FS does not answer to around 20-30 REGISTERs each day.
I am trying to understand that, as the server is far from loaded (max 100 concurrent calls on a Dell R610).

Can anyone recommend some debugging steps to try to narrow this down ?
Any known issue of this sort in 1.6.6 ?

Thank you
