Comment (by jmr@…):

 The ftruncate failure happens when squid is starting up again ''after'' it
 has exited abnormally (and thus not unlinked its shared memory segments
 before exiting). So the actual problem is whatever is causing the abnormal
 termination before squid restarts and prints that message.
