Services Hung, and End Users Can’t Connect–Orphaned Locks

This condition may be caused by a control thread, which holds a Berkeley DB database page lock, quitting without releasing the lock. To confirm the problem, run pstack on cshttpd processes and csadmind. (pstack is a standard UNIX utility found at: /usr/bin/pstack) It should show threads that are waiting to acquire a lock.

To fix the problem, restart Calendar Server, as follows:

1. Change to the directory where start-cal resides.

   cd cal_svr_base/SUNWics5/cal/sbin

2. Issue the start-cal command.

   ./start-cal
