I'm also can not work around this bug. I need to emulate behavior of some proprietary log system, that always names log files as "module_yyyyMMddHHmmss.log" and rolls over only by file size trigger.

I'd like to use pattern like "module_%d

{yyyyMM}

%d

{ddHHmmss,aux}

.%i.log" with size based trigger. It's suitable to roll each month too, but when file size trigger acts, it creates new file with the same time stamp and new number. Actually I don't need the %i token because the log file can not overflow in one second. But omitting the %i token leads to NPE.
