> Jira TRAFODION-2927 refactored the UPDATE STATISTICS logging logic to use the 
> CommonLogger class. Unfortunately, this introduced a problem that sometimes 
> causes cores in CommonLogger::buildMsgBuffer. The UPDATE STATISTICS code 
> passes raw data via a "template" parameter to the logging layers. The logging 
> layers interpret this template like a printf template. So, if the data 
> happens to have a substring such as %d or %n in it, the logger code expects 
> an additional argument to supply a substitution value for it. But none is 
> supplied so we abend.
> A workaround is to turn automatic logging off, e.g. by setting CQD 
> USTAT_AUTOMATIC_LOGGING 'OFF' in the "_MD_".DEFAULTS table.
