my guess would be that your Pd process has run out of file-handles.

to check, get the PID of the pd process ("ps aux | grep -w pd"), and 
then use  `lsof -p $PID`, or simply "ls -lha /proc/$PID/fd".

to see the allowed number of simultaneously open files, use "prlimit -p 
$PID", or simply "cat /proc/$PID/limits".

most likely a bug in some external, that opens files but doesn't close 
them (i would have expected this to pop up earlier/more often, if it was 
a problem in Pd itself)
