Hi,
My application is getting crashed with SIGABRT on Vmware (Esx 3.5 & Esx 4) when
it sends the event to Syslog host (using UDP Port# 514). But, syslog port 514
is blocked by Esx Firewall by default. I added try & catch block to
LOG4CXX_INFO(loggerSyslog, syslogBuf) macro and it didn't help.
The Application runs very well if Syslog's port 514 is open by firewall.
Is there any way to avoid the application crash even if syslog's port 514
blocked by firewall? I would like to avoid checking the firewall status on
Syslog's port 514 each time before I send the event to Syslog host.
Here are the versions I use:
apache-log4cxx-0.10.0
apr-1.2.12
apr-util-1.2.12
As per the stack trace of core file:
The application throws IO Exception at:
// send the datagram packet
apr_size_t len = p->getLength();
status = apr_socket_sendto(socket, addr, 0,
(char *)p->getData(), &len);
if (status != APR_SUCCESS) {
throw IOException(status);
Here is the stack trace of core dump:
terminate called after throwing an instance of 'log4cxx::helpers::IOException'
what(): IO Exception : status code = 1
Unable to get event information. status: 1Unable to get event information.
status: 1
Program received signal SIGABRT, Aborted.
