<nf>/init.c:<nf>_main() : ogs_pollset_poll() receives the time of the expiration of next timer as an argument. If this timeout is in very near future (1 millisecond), and if there are multiple events that need to be processed by ogs_pollset_poll(), these could take more than 1 millisecond for processing, resulting in the timer already passed the expiration. In case that another NF is under heavy load and responds to an SBI request with some delay of a few seconds, it can happen that ogs_pollset_poll() adds SBI responses to the event list for further processing, then ogs_timer_mgr_expire() is called which will add an additional event for timer expiration. When all events are processed one-by-one, the SBI xact would get deleted twice in a row, resulting in a crash. 0 __GI_abort () at ./stdlib/abort.c:107 1 0x00007f9de91693b1 in ??
