[LON-CAPA-admin] lonsql_errors file

[Stuart Peter Raeburn]

Jon, 

Something is amiss if you're seeing a lonsql_errors file of several Gb.
What does tail -100 /home/httpd/perl/logs/lonsql_errors show? 

Apparently errors are being logged when 
/home/httpd/perl/parse_activity_log.pl is run. Of course errors are most 
likely being logged at other times too. 

parse_activity_log.pl is run by the lonsql daemon when a student's activity 
in LON-CAPA is displayed by a Course Coordinator using adm/trackstudent 
(called via the "View recent activity by this student" link a User's 
information page displayed to a CC in a course in which the student is 
enrolled).
