PHP memory error, but caused by a browser?
 

I've had an isolated report of a php out of memory error (Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 10250 bytes) in /var/www/forums/showthread.php on line 1268), but it's only reproducible on 64bit Firefox 3.0.10 on Windows Vista 64.

Forum version is 3.7.6.

There is more information in this thread: http://forums.johnstonefitness.com/s...ad.php?t=47710

I've bumped the PHP max memory from 16MB to 32MB and even 64MB.

How could a specific browser be causing a server-side error like this?
