Hello,
  When the configure value of priority_boost or flush is larger than INT_MAX,
auditd is still started successfully. The priority_boost_parser and flush_parse 
code use an int variable to store the result strtoul() and then compared with 
INT_MAX.
  The attached patch fixes the problem in src/auditd-config.c and 
audisp/audispd-config.c.
Regards
Chu Li
