Sometimes when a server hangs, the operating system may display an abend (Abnormal End) message entitled "CPU Hog Timeout." This message appears after the CPU Hog Timer kicks in. This type of abend allows the server to break out of the hung condition. It can then either continue server operation, or drop you into a debugger operation if you've disabled automatic restarts following abends.

When the CPU Hog Timer kicks in, the hung state is not preserved on the server. However, for debugging purposes, you may find it useful to examine the server in the hung state. To prevent the CPU Hog Timer from disrupting the server state during the hang condition, enter the following SET parameter at the server console prompt:

SET CPU Hog Timeout Amount = 0
