However, even other functions sometimes cause a crash (I removed the above ones). The situation in the latest snapshots remains the same. It looks like a poor thread synchronisation. Apache 2.2.x used. Reproduce code: --------------- This should work fine: http://php.net/manual/en/function.curl-multi-exec.php#48813 ..but you may have to increase the number of links in $connomains, or change them to pictures. Expected result: ---------------- The code doesn't crash the webserver. Actual result: -------------- The code often crashes the webserver (not always). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37171&edit=1
