lsyncd fails on FreeBSD system

I can successfully copy the css folder, yet cannot copy the newsimages folder. The lsyncd service keeps stopping. * If lsyncd is pointed at the /pool/www/yiiazertag/azertag/css/ folder, it works fine.

-session
    root@main2:/ # service lsyncd status
    lsyncd is running as pid 2044.

The log file reports:

* However, if lsyncd is supposed to work with /pool/www/yiiazertag/azertag/newsimages/, it does not work any more:

-session
    root@main2:/ # service lsyncd status
    lsyncd is not running.

The file limits should not pose a problem: | sysctl | value | |:---------------------- | --------:| | kern.maxfiles | 500000 | | kern.maxfilesperproc | 490000 | | kern.openfiles | 274 |
