Hi,

I am using NXLog with the Example 108. “File Rotation Based on Size” from the NXLog Community Edition Reference Manual.

In rare cases i have the problem that rotate_to uses the wrong filename and overwrite some other logfile. In the example below “logid.log” to “Mod-002”.  See nxlog.log

Version:  nxlog-ce-3.1.2319

nxlog.log

Zeile 3644025: 2023-03-14 10:28:02 INFO om_file successfully rotated file 'C:\Program Files\nxlog\data\10.87.243.24\logid.log' to 'C:\Program Files\nxlog\data\10.87.243.24\Mod-002.20230314102802.log'

nxlog.conf

	Exec		if udpfile->file_size() > 5M { \
					$newfile = '%LOGDIR%\' + $Hostname + '\' + $SourceName + '.' + strftime(now(), "%Y%m%d%H%M%S") + '.log'; \
					udpfile->rotate_to($newfile); \
					exec_async('%CONFDIR%\\bzip2.exe', $newfile); \
				}
</Output>

<Route udp>
	Path		udp => udpfile

Any ideas what's going wrong here?

Thanks
