Warnings about file locking

[Adrian Barker]

In the syslog files we see a number of errors of the form:

Nov 13 02:13:11 pop-b.ucl.ac.uk mailscanner[20961]: Failed to lock /var/spool/mqueue.in/qfCAA21422: Resource temporarily unavailable

Does anyone know what these mean, and what should be done about them ? It does not
look like a load-related problem, as they occur throughout the day and night.
The machine is running Solaris 8.


Thanks for any suggestions,
