I dont know what this is ... some kind of attack? Only this set of IPs are producing this error, no one else.

line 277 in functions.php is

$contents = str_replace('<navigation>', build_breadcrumb(1), $contents);

which is part of the PARSE_PAGE function.

My memory limit is 128mb after talking to the host and getting them to increase the limit just in case... this has not solved the issue.

Please, any help?

That PHP error occurs when the allowed memory size is exhausted (the Random Access Memory).. That's not an attack, that's not a MyBB problem, that's your host's server problem..

There's no reason that code should be exceeding your memory limit.

That's the point Matt - and it's only happening from these China IP addresses ... The forum gets 5-7k visitors per day and i only see these errors from these China IP addresses ... and its once or twice a minute..

Strikes me as dodgy..or weird ... any suggestions?

Ask your host to increase value of max_allowed_packet attribute, that might help.
