Ошибка: lock manager out of room
Go to the interbase/bin directory (Windows) or /usr/interbase (Unix) and locate the configuration file isc_config. By default your configuration file will look like this:
I increased the V4_LOCK_MEM_SIZE entry from 98304 to 198304 and things were fine then.
!!! Important !!!
By default all lines in the config file are commented out with the leading # sign. Make sure to remove the # sign in any line that you change - the default config file just shows the default parameters.
