Re: Sporadic 'Connection refused' errors in 4.2.4

I saw the missing info in the post so I figured that could be the issue.

When you say "Same old connection refused errors again on the checks I re-enabled." are you having that error all of the time or is it intermittent still?
If it is intermittent, you may try increasing the timeout to a higher value that what you have and see if that helps. Of if you have access to the host, check it's log to see if there are any clues there.

If it is happening all of the time, run the check in the command line with the -v (Verbose) and post the output here.

Just sometimes, and re-enabling those checks seems to kick others off that were fine.

I've tried upping timeouts and it doesn't really seem to do anything, 99% fine, then the old connection refused stuff.

Running command line checks all day - work 100% but I will add -v to check this time.

I've always thought this was a problem with forking off processes to do the service checks, since the start.

I am trying to see if I can replicate the Sporadic Connection Refused to the servers you are testing. One of the servers I cannot connect at all and the other seems to be redirecting the page but so far it is working.
One thing to check, see if the ISP that are hosting those sites are throttling connections, etc. and see if that is happening.

Hi, I've check with my hosting providers and none of them have any connection throttling in place.

Thanks.
