hi guys,
i am not sure if this is right list, but anyway, let me share with you a
problem. I am developing a big distributed system, as Ph.D. job, and
i'am using xml for parsing incoming messages.
All the messages arrive to a daemon which parse them using
xmlParseMemory after forking a process. Everything works fine, but i
have a trouble when testing stressing behavior; i mean when a lot of
messages comes to the daemon with an small interval of time (less than
0.2 seconds). What happens is that sometimes xmlParseMemory returns
NULL. I am sure that the input parameter has the xml message, and the
problem disappear when a waiting time (sleep 0f 0.2 seconds) is included
between messages.
doc = xmlParseMemory((char *)out, strlen(out));
if (doc == NULL ) {
// sometimes falls here ;-((
hD_logerror("%s: xml_msg not handled successfully\n", I_AM_TAG);
query_rspn(hD_E_XML_FAIL_CH, hD_E_XML_FAIL400_CH, "DM2 xml_msg
not handled successfully", response_xml);
xmlFreeDoc(doc);
return (-1);
}
i use red hat 7-3 and
libxml2-2.4.10
any idea ?
have you heard about it before ?
thanks in advance,
Hector
