Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip The memory leak problem has been corrected, can you please check if the phpinfo() still drives up the load. Previous Comments: ------------------------------------------------------------------------ [2002-10-09 13:26:20] [EMAIL PROTECTED] --disable-debug affects the display of the memory leak :-) It does not affect the error itself. Still an increasing load. I've added some trace warnings, and it seems that every string is passed through php_escape_html_entities twice! Here's an anonimized snippet: PHP Warning: oldlen is 15. old is <SERVER_SOFTWARE>, newlen=1210382182, all=1, quote_style=2, hint_charset is <(null)> in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Putting a terminator at position 15 in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Returning replaced <SERVER_SOFTWARE> (len=15) in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: oldlen is 15. old is <SERVER_SOFTWARE>, newlen=1211165388, all=1, quote_style=2, hint_charset is <(null)> in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Putting a terminator at position 15 in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Returning replaced <SERVER_SOFTWARE> (len=15) in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: oldlen is 34. old is <Apache/2.0.43 (Unix) PHP/4.4.0-dev>, newlen=1210382258, all=1, quote_style=2, hint_chars et is <(null)> in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Putting a terminator at position 34 in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Returning replaced <Apache/2.0.43 (Unix) PHP/4.4.0-dev> (len=34) in /webdocs/host.domain.nl/public_html/php 2345.php on line 2 PHP Warning: oldlen is 34. old is <Apache/2.0.43 (Unix) PHP/4.4.0-dev>, newlen=1211165388, all=1, quote_style=2, hint_chars et is <(null)> in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Putting a terminator at position 34 in /webdocs/host.domain.nl/public_html/script.php on line 2 PHP Warning: Returning replaced <Apache/2.0.43 (Unix) PHP/4.4.0-dev> (len=34) in /webdocs/host.domain.nl/public_html/php 2345.php on line 2 ------------------------------------------------------------------------ [2002-10-07 06:41:36] [EMAIL PROTECTED] The problem is in the recent changes to ext/standard/info.c which is calling php_escape_html_entities (via php_info_html_esc) and PUTS()-ing the result. It never efree's it. I suspect the loading problems will go away if you build a --disable-debug version of PHP. ------------------------------------------------------------------------ [2002-10-06 23:09:07] [EMAIL PROTECTED] PHPAPI char *php_escape_html_entities(unsigned char *old, int oldlen, int *newlen, int all, int quote_style, char *hint_char set TSRMLS_DC) { int i, j, maxlen, len; char *replaced; enum entity_charset charset = determine_charset(hint_charset TSRMLS_CC); int matches_map; maxlen = 2 * oldlen; if (maxlen < 128) maxlen = 128; replaced = emalloc (maxlen); // #line 667 len = 0; i = 0; while (i < oldlen) { .... } } replaced[len] = '\0'; ... So what happens if oldlen = 0 and more importantly: how can oldlen become 0? ------------------------------------------------------------------------ [2002-10-06 23:01:29] [EMAIL PROTECTED] hmm......that is a hint: /home/mdev/cvs/php4/ext/standard/html.c(667) : Freeing 0x0820BA24 (396 bytes), script=- Last leak repeated 383 times 383 times? ------------------------------------------------------------------------ [2002-10-06 22:57:30] [EMAIL PROTECTED] No change at all.
