csyslogd crashed when trying to read alerts.log file, at the line starting 
with '** Alert'. 
For example, 
** Alert 1368839704.12015: - pam,syslog,authentication_success,

It was trying to allocate memory for the alertid (e.g., 1368839704.12015) 
but failed to do so. 

If you can identify the alerts.log file lines when this happened, it may be 
useful.
Also, which XML tag was causing it?
