Lots of Forbidden - Permission denied messages

[FrancisChung]

Hi there,

I've recently been getting a lot of the following error messages.

I can't see anything on the error logs that the ProcessLog Module provides.

I thought it could be a problem with the DNS, so i changed it to OpenDNS but to no success.

Is there anything else I should check?

If it's a plug-in, what can I do to find out which plug-in it is, besides turning each one off one by one?

Thanks in advance!

Forbidden

You don't have permission to access /processwire/XXXXX/ on this server.

That looks like a filesystem error. Sure the running webserver does have permission to read those directories?

[FrancisChung]

Not sure why my permissions would change all of a sudden? 
I have run the  Processwire Diagnostics before, but I can run them again to check permissions.

Also, the errors are occurring randomly.

If it was a strict permissioning issue, it wouldn't run at all full stop, no?

[FrancisChung]

This is what the Diagnostics returned.

Using a different browser (Safari for this test, usually using Chrome) seems to make no difference.

I've cleared the cache on Chrome as well, to no success ....

Looks like Apache had too many open files (?).

Rebooting Apache seems to have fixed it.

I do have a lot of tabs open on Chrome. Guessing that could be a possible candidate for failure.

I tried this and it seems to have fixed it, but my open file limit only went up to 4,000 from 256.

If you're using MAMP, you need to goto the MAMP directory and look for my.cnf

(I think under tmp)

I also tried this on the operating system level, but didn't work too well. 

I will revist when the first solution stops working.

Turns out, the above didn't work too well.

I'm having to manually increase the limits for now using the following command.
 

sudo launchctl limit maxfiles 655356 655356

I'm still getting the odd errors, but the frequency far far less and it's managable.

P/S I also found out this is due to a bug in XDebug where it's not closing all the file handles it is opening. Unfortunately, it still hasn't been fixed yet. The XDebug module I'm using is part of MAMP Pro. I guess the alternative is to setup Zend Debugger, but I didn't managed to get it work the first time I attempted it.
