[gentoo-user] syslog-ng: reporting no space though there's plenty

[hw]

Hi,
syslog-ng keeps reporting:


Mar 23 17:34:41 sunflo-mx syslog-ng[27532]: Error suspend timeout has 
elapsed, attempting to write again; fd='15'
Mar 23 17:34:41 sunflo-mx syslog-ng[27532]: Suspending write operation 
because of an I/O error; fd='15', time_reopen='60'


while there's plenty of disk space available.  Restarting it didn't 
help.  This is from an LXC container --- could there be some disk limit 
in effect by default which I don't know about?
