No more record locks are available. The system lock table is full.
Try again later, when more locks might be available.
The symbolic name for this error is ENOLCK, errno=46.
Perhaps a process called fcntl(2) with the F_SETLK or F_SETLKW option, and the system maximum was exceeded. The system contains several different locking subsystems, including fcntl(2), the NFS lock daemon, and mail locking. All subsystems can produce this error.
