I have big traffic (at least 100 computers) , and squid often crashed in
Comm::DoSelect(int msec) function.
I have interception mode and NAT redirect.
In coredump I saw then bug is in next fragment of code:
446│ for (size_t loopIndex = 0; loopIndex < nfds; ++loopIndex) {
447│ fde *F;
448│ int revents = pfds[loopIndex].revents;
449│ fd = pfds[loopIndex].fd;
450│
451│ if (fd == -1)
452│ continue;
453│
454├> if (fd_table[fd].flags.read_pending)
455│ revents |= POLLIN;
SIGSEGV occured often (about 1 time in a minute) in line 454 : fd=-66012128
, loopindex=283
(gdb) p pfds[282]
$17 = {fd = 291, events = 64, revents = 0} -- looks ok
(gdb) p pfds[283]
$18 = {fd = -66012128, events = 32595, revents = 0} -- looks strange and
spoiled
(gdb) p Biggest_FD
$19 = 292
Please, could you fix it.
Thanks.
