Sorry typo again, was 3GB (not 3MB) the total consumed memory by several
char[]. For example I reveived a 60MB utf8 json and I see it resides inside a
250MB char[] I have attached a dump screenshot
Not sure if is relevant but I use RollingFile :
<RollingFile name="PROJECT"
fileName="${sys:catalina.home}/logs/@webapp.name@.log"
filePattern="${sys:catalina.home}/logs/@webapp.name@.%d{yyyy-MM-dd}.log">
<PatternLayout pattern="%d{ABSOLUTE} %-5p %mdc{ApiKeyOrEmail}-%mdc{tid} [%c{1}]
%m%n"/> <filters> <ThresholdFilter level="@log.level.project@"
onMatch="NEUTRAL" onMismatch="DENY"/> <MarkerFilter marker="API_RESPONSE"
onMatch="DENY" onMismatch="ACCEPT"/> </filters>
<TimeBasedTriggeringPolicy/> </RollingFile>
I will try to reproduce if needed

That's the bug I was trying to find. It sounds related.
