Under heavy usage, stunnel-4.20 on AIX 5.3 enters into a loop with high CPU load. SSL_accept() returns with error, SSL_get_error() returns 5 (SSL_ERROR_SYSCALL). get_last_socket_error() returns EAGAIN, and the loop continues without end. Nevertheless, new connection requests still get processed.

Could it be the problem described at the end of this page: https://www.systinet.com/doc/ssc-65/waspc/html/extlibs.install.openssl.html

Indeed. Further experiments on AIX 5.3: OpenSSL 0.9.8e configured as "./Configure no-idea threads", compiled with "cc" (IBM XL C Compiler 7.0), stunnel 4.20 --> loop in init_ssl() OpenSSL 0.9.8e configured as "./Configure no-idea threads", compiled with "xlc_r" (IBM XL C Compiler 7.0, thread-safe variant), stunnel 4.20 --> no problem OpenSSL 0.9.8e configured as "./Configure no-idea threads", compiled with "gcc" (GCC version 4.1.1), stunnel 4.20 --> no problem Thanks for the hint. -- Regards Peter Heimann _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.
