Adding the try/except "helps" ... some print's lead me to belive that the error is actually EWOULDBLOCK and not EINTR. I moved zopeinstancehome and I am starting Zope with a clean Data.fs and no Products. This version seems to be more stable. I'm going to slowly add in Products until I can crash it again and I'll try to post any results later ... On Thu, 16 Aug 2001 11:22:18 -0400 John Ziniti <jziniti@speakeasy.org> wrote:
Thanks, Toby ... my asyncore has no try/except:
from $PYTHON_SOURCE/Lib/asyncore.py
for fd, obj in map.items(): if obj.readable(): r.append (fd) if obj.writable(): w.append (fd) r,w,e = select.select (r,w,e, timeout)
if DEBUG: print r,w,e
What's up with that.

I am moving this thread over from the zope list in the hope that someone here may have more insight into the nature of this problem, and perhaps how to go about better diagnosing/fixing the problem.
To sum up: Under apparently random circumstances and rather mild amounts of traffic, Zope is crashing and printing the Traceback below to the console. This is Zope-2.4.0, Python-2.1.1 on SunOS 5.8/Sparc.
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')
Any ideas?
Im not using that version of Zope or Python, but in every version of asyncore I have seen the call to select is wrapped with a try/except that traps EINTR, and retries. The version I happen to be using at the moment looks like:
try: r,w,e = select.select (r,w,e, timeout) except select.error, v: if v[0] != EINTR: raise else: break
Unless your version is different, that traceback 'shouldnt happen'
