Using demonstration script 2 I only get an error indicating that the memory limit (8MB) has been exhausted.

Install PHP 4.1.x (whether .1 or .2) and suddenly Apache begins growing, and growing, and GROWING in memory use. Eventually a malloc/segfault occurs and Apache either restarts or simply fails outright. Reverting to 4.0.6 resolves the issue, placing 4.1.x back on reintroduces it. No Zend, no nothing other than GZIP and MySQL. Since numerous malloc/segfaults end up leaving Apache unable to restart itself, and PHP 4.1.2 was a security fix and thus HAD to upgrade to it (previously just stuck with 4.0.6 due to this), I have had to configure Apache to auto-restart itself every few hundred hits - this seems to prevent the fault occurring. Mind you PHP still fills up the error log with sh#tloads of parse errors - out of say several hundred executions of a simple 1 line script for example it'll suddenly decide on the next excution to suffer a parse error. Again specific to PHP 4.1.x Sorry if this isn't the same fault? ------------------------------------------------------------------------ [2002-04-02 10:24:07] wolfram@schlich.org why not? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
