Hi all,

I'm using Kamailio timers to execute a series of calls with a certain delay. I have found out that from time to time, the timers are triggered too soon, sometimes they are triggered 2/3 seconds before they should.

There is nothing significant in the logs, some of the log lines previous to the premature call are:

10(16136) DEBUG: tm [timer.c:606]: wait_handler(): WAIT timer hit @1111936903 for 0x7f32cc4eede8 (timer_lm 0x7f32cc4eee70)
10(16136) DEBUG: tm [timer.c:643]: wait_handler(): finished transaction: 0x7f32cc4eede8 (p:0x7f32cc34ee90/n:0x7f32cc34ee90)
10(16136) DEBUG: tm [h_table.c:132]: free_cell_helper(): freeing transaction 0x7f32cc4eede8 from timer.c:652

And some other ones after the call are

10(16136) DEBUG: tm [timer.c:494]: retr_buf_handler(): timer retr_buf_handler @1111937043 (0x7f32cc4efa18 -> 0x7f32cc4ef9f8 -> 0x7f32cc4ef6d8)
10(16136) DEBUG: tm [timer.c:545]: retr_buf_handler(): new interval 2000 ms / 16 ticks (max 4000 ms)
10(16136) DEBUG: tm [timer.c:329]: retransmission_handler(): request resending (t=0x7f32cc4ef6d8, SUBSCRIBE ... )
10(16136) DEBUG: tm [timer.c:573]: retr_buf_handler(): timer retr_buf_handler @1111937043 (0x7f32cc4efa18 ->0x7f32cc4ef9f8->0x7f32cc4ef6d8) exiting min (16, 24)

I have read in the documentation that it is normal to have a bit of delay in some of the timers, but it doesn't mention anything about this behavior. Is this normal?

Thank you.
