select.error: (4, 'Interrupted system call')
Hey all, I've been getting this all day today since I upgraded to Python 2.1.1 and Zope-2.4.0. It seems to happen randomly, but mostly when I am moving around the ZMI, the more I move around, the more likely it is to occur. It also brings down the Zope server, requiring a restart and is thuis rather annoying. Any ideas on causes, fixes, hunches? The traceback (printed to console) follows. Traceback (most recent call last): File "/u01/zope/Zope-2.4.0-src/z2.py", line 774, in ? asyncore.loop() File "/u01/zope//lib/python2.1/asyncore.py", line 194, in loop poll_fun (timeout, map) File "/u01/zope//lib/python2.1/asyncore.py", line 86, in poll r,w,e = select.select (r,w,e, timeout) select.error: (4, 'Interrupted system call') Thanks in advance, Ziniti -- John Ziniti Channing Laboratory Brigham and Women's Hospital 181 Longwood Avenue Brookline, MA 02115 john.ziniti@channing.harvard.edu

Geez. I'm not sure, John. This error is being raised by the OS in the middle of a system call. I don't know enough about Solaris to be able to give you any direction. Perhaps someone else can chime in? Anybody else seen this? John Ziniti wrote:

In my application area, an error like that would mean: - you blocked on a set of file descriptors - either - someone tried to kill you, so you clean up and then exit or - a timer went off so you handle it and then block again Is it possible to handle signals in python and find out who's sending them? Is it running in a terminal (could be ^c'd) or as a daemon (could get SIGTERM on change of run-level) ? Do any other processes on this box incurr stray fingers of G_d?

Could do. The old unix semantics say you deliver a signal to a process. After the process has split itself into a bunch of threads, it's unclear which one will get to handle it. I suspect SunOS favours ones that are blocked, which would make sense if they were blocked in sigsuspend, waiting for a signal, but that's not your situation :-) This conversation may belong on the zope-devel mailing list, where I expect they have people who understand which signals Zope is supposed to accept, and how.
