+Summary: Hang exiting a threaded program
|
||
|
|
+
|
||
|
|
+We have a helper program in Beagle which uses threads and async IO to talk
|
||
|
|
+over a unix domain socket to the beagle daemon. About one time in ten the
|
||
|
|
+app will hang after the last line of the app runs and never exits. The
|
||
|
|
+thread that does the IO seems to work fine; the data is sent successfully
|
||
|
|
+to the remote side, but I'm not sure how to debug threads further.
|
||
|
|
+
|
||
|
|
+This is using both 1.1.7 on Ubuntu and 1.1.7.3 on SUSE 9.3. The debugging
|
||
|
|
+info that follows is from Ubuntu.
|
||
|
|
+
|
||
|
|
+Attaching strace to the program, it prints:
|
||
|
|
+
|
||
|
|
+futex(0x81a4170, FUTEX_WAIT, 1, NULL
|
||
|
|
+
|
||
|
|
+and never exits. gdb backtrace:

+The blocking on the futex is also what happens in bug 75007.
