#31558 [Opn->Fbk]: FATAL: erealloc(): Unable to allocate ### bytes

ID: 31558 Updated by: tony2001@php.net Reported By: jdw at nearlyfreespeech dot net -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: FreeBSD PHP Version: 4.3.10 New Comment: What's your PHP configuration? Any Zend modules enabled? Any chance to replicate the problem with strace httpd -X? The info you've provided is pretty useless ATM as we don't have your configuration and we're unable to reproduce the problem. Previous Comments: ------------------------------------------------------------------------ [2005-01-14 19:44:06] jdw at nearlyfreespeech dot net Description: ------------ We have seen this error under the following conditions - FreeBSD 4-STABLE - Using Apache 1.3.33 - PHP 4.3.10 - multiple servers - servers have hundreds of megs of available RAM and gigs of free swap - httpd processes are well within resource limits - happens with random PHP scripts, even simple pages that don't use much memory - pages that generate the error may work if immediately reloaded (unchanged with respect to code and data), suggesting that this is not a per-request memory limit being exceeded - almost always happens *before* headers are sent - occurs on pages not using gzip or zlib or output compression or anything else that would defer content output - happens with alloc amounts from 7500 bytes to about 1meg, averaging between 100-300k. - happens in repetitive "clusters" Problem persists across "apachectl graceful" but "goes away" (for awhile at least) after "apachectl restart" so the Apache parent process may tie in somehow. Is there a way I can obtain more helpful debug information about this in a production environment? Thanks for any help with this! Reproduce code: --------------- n/a... virtually any PHP page appears susceptible, which is consistent with the observation that it occurs before headers are sent. Expected result: ---------------- PHP script should run. Actual result: -------------- Example from Apache error log: (all messages appear in immediate succession) FATAL: erealloc(): Unable to allocate 7500 bytes FATAL: erealloc(): Unable to allocate 7500 bytes FATAL: erealloc(): Unable to allocate 7500 bytes FATAL: erealloc(): Unable to allocate 7500 bytes FATAL: erealloc(): Unable to allocate 7500 bytes FATAL: erealloc(): Unable to allocate 7500 bytes ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31558&edit=1
