Older versions of elogd have a problem with sending long attachements - the send() syscall is not protected against interrupt by SIGALARM. This seems to be fixed in non-SSL builds of current elog (version 3+), 
but for SSL builds, the error handling for the SSL_write() function looks incorrect. In addition, from OpenSSL documentation it is not clear if SSL_write() can handle signal interrupts at all.
