http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21285 (mem) cache size becomes negative causing segfault ------- Additional Comments From [EMAIL PROTECTED] 2003-07-02 18:17 ------- The problem shows up on only with dynamic object generation. We have tested it using PHP and a small number of simple http clients. How to reproduce the problem: Send object requests from some (2-3) clients (I wrote a simple client that at max rate possible connect to server, post a GET request, read reply and close the connection) to a simple php script (code follows) with the cache object count very very small (Es. : MCacheMaxObjectCount 50). The script produces different small objects (a few bytes in size) based on an input variable (pippo.php?variabile=1234). If you look at the cache size after some time you see it decrease to zero and become negative. Eventually, some of the threads die because of a segfault. -------- Apache (2.0.46) configure command ------------- ./configure --with-mpm=worker --prefix=/apache-test/ --enable-mods-shared=all --enable-so --enable-cache=shared --enable-mem_cache=shared ----- Cache configuration ------------- # # Sample Cache Configuration # <IfModule mod_cache.c> <IfModule mod_mem_cache.c> CacheEnable mem / CacheDefaultExpire 1000 CacheMaxExpire 3000 CacheIgnoreCacheControl Off CacheIgnoreNoLastMod On MCacheSize 2000 MCacheMaxObjectCount 50 MCacheMinObjectSize 1 MCacheMaxObjectSize 1048576 </IfModule> </IfModule> ---- php script code (pippo.php) ---- <?php header("Expires: Mon, 26 Jul 2005 05:00:00 GMT"); echo "<head> </head>"; echo "<html> <br> html part <br> </html>"; if (isset($_GET["variabile"])) { echo "mi hai passato ".$_GET["variabile"]; } else { echo "non mi hai passato niente"; } ?> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
