Summary | 0001064: Denial of Service causes lockup instead of graceful crash. | ||||||||||||
Description | Pretty much exactly what it says on the tin. One of my servers was hit with a program that seemed to rapidly have clients connect and disconnect from various IP addresses with random names, and this occurred until the program finally froze. I consider the program locking up a bug, since ideally it would at least crash gracefully so it could be automatically restarted. | ||||||||||||
Additional Information | Here is the strace output from the locked-up process: gettimeofday({1348626188, 367165}, NULL) = 0 recvfrom(12, 0x8eebaa0, 131072, 0, 0xbfe4d298, 0xbfe4d2a8) = -1 EAGAIN (Resource temporarily unavailable) nanosleep({0, 1000000}, NULL) = 0 These three system calls are repeated 10,000,000 times a second. Perhaps this might provide some insight into what is going on. | ||||||||||||

Disregard the initial symptoms. I can't actually confirm why the server went down, only that it did lock up and I got some strace output that might be useful. |
