Package: lighttpd
Version: 1.4.13-4
Severity: important
Hi,
Lighttpd entered an infinite loop and uses 100% CPU. Strace shows the loop:
time(NULL) = 1180962549
poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}, {fd=11, events=POLLIN}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=9, events=POLLIN},
{fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, {fd=-1}, ...], 71, 1000) = 1
ioctl(12, FIONREAD, [0]) = 0
read(12, "", 2303) = 0
time(NULL) = 1180962549
fd 9 is ready but isn't serviced, so the next call to poll returns immediately.
