Hi!

I have a problem where a configure script is hanging. I first saw the behavior in 1.5.18, and it's still there in the latest snapshot. The only machines that we are seeing it hang on are windows 2000 machines, sp4, with duel pentinum 933 mhz processors, and using ssh to login to the machine. I haven't been able to reproduce the problem on single processor machines or when ssh is not used.
Under 1.5.18, the hang occurred about 1 in ten times in the test_configure script (provided in the bash_test.tar.bz2 file. Under the latest snapshot it's about 1 in 900.
When the hang happens it appears that a process is completed, but still can be found in the process directory. The cmdline file says <defunct>, but the process still shows up in the process list (ps - ef). If I try to clean up by killing the process, the kill command says that the process doesn't exist. The only way that I can make the hung process go away is by using the task manager to kill the process.

Your symptoms look familiar to our OOo build hang. I'm curious if in your case a:

$ ls /proc/<hangpid>/fd

also cures the hang. (Sometimes this has to be issued several times.)

This didn't seem to do anything for me.....but I also did not try several times, and now I'm having a hard time reproducing the problem. :(


One really odd thing that I did notice on my windows 2000 machines was that when I do a 'ps -ef' many times in a row quickly, the test_configure script that I'm using dies...it either segfaults or I get fork: Resource Temporarily unavailable.
