I've been running Courier and in the past weeks it started getting time out errors intermittently. I wrote a Python script to test it (runs every minute):
Code:
import poplib, time, urllib, socket, getpass
socket.setdefaulttimeout(30)
from datetime import date
if True:
try:
#print "1/2\n"
o = open('output.txt', 'a')
opener = urllib.FancyURLopener({})
f = opener.open("http://www.myserver.com/up.php")
strn = f.read()
ok = time.strftime("%a %b %d %H:%M:%S %Y") + "- 1/2 Site Status:"+strn+"\n"
o.write(ok)
o.close()
except Exception, er:
pr = time.strftime("%a %b %d %H:%M:%S %Y")+"- 1/2 URL error: "+er+"\n"
o.write(pr)
o.close()
try:
#print "2/2\n"
o = open('output.txt', 'a')
M = poplib.POP3('myserver.com', 110, 30)
M.user('me@myserver.com')
M.pass_('pass')
numMessages = len(M.list()[1])
k = time.strftime("%a %b %d %H:%M:%S %Y")+"- 2/2 POP Okay. Messages: "+str(numMessages)+"\n"
o.write(k)
o.close()
except Exception, e:
prnt = time.strftime("%a %b %d %H:%M:%S %Y")+"- 2/2 (Site Status:"+strn+") POP Error:"+str(e)+"\n"
o.write(prnt)
o.close()
I see things like this:
Code:

What would be causing this? The logs show that the web server is up and running just fine during these times.
I've submitted a ticket to my support for the server, but they keep saying it's fine (they telnet to it once, it connects and they report it is fine).
