When a TCP timer is stopped, t_timers[] is set to SBT_MAX. Adding the corresponding t_precisions[], if it is not zero, would result in overflows in tcp_timer_next(). To avoid this, skip stopped timers. The problem was identified while debugging uperf by Lukas Book and an initial patch was provided by him. The committed patch was suggested by glebius. The problem can be observed by running netstat -nxptcp and looking for negative timer values and by observing very long running timers in some cases.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
