Several customers have found delta-syncrepl will lock up after a time. Today it occurred again, and this time some logging data was able to be gathered. The last operation logged was a MOD op. This matches past lockups, which were also either MOD or ADD operations.
The following files will be uploaded to the ftp site, where # will be the assigned ITS number.
#-dbstat.delta.out.2007-10-01
which is the db_stat information for the accesslog DB
#-db_stat.out.2007-10-01
which is the db_stat information for the main DB
#-pstak.out.2007-10-01
which is the pstack information for the slapd process
Unfortunately no GDB info was retrieved this time, and reportedly gcore hung.
The most interesting part is I see no WRITE locks held in either DB, and all the client threads are hung in a mutex.
