Alex Rudyy updated QPID-8004:
-----------------------------
Description:
When "Maximum Number of Rolled Files" is configured on FileLogger and the
number of rolled files reaches the maximum, the broker can scans file system 60
times submitting a scan task every 5 seconds.
{{RollingPolicyDecorator.ScanTask}} takes into account only file names to
detect new rolled files. Thus, when the number of rolled files reaches the
maximum on the FileLogger with {{SizeTriggeringPolicy}} rollover policy, the
names of the rollover files remain the same as old files are deleted and
remaining files are renamed to match {{fileName + ".%i"}} where {{%i}} is a
file index starting from {{0}}. {{RollingPolicyDecorator.ScanTask}} can be
improved to take into consideration last modification or creation time to
detect the new rolled over files correctly.
