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:

#V4_LOCK_MEM_SIZE                       98304

#ANY_LOCK_MEM_SIZE              98304

#V4_LOCK_SEM_COUNT              32

#ANY_LOCK_SEM_COUNT          32

#V4_LOCK_SIGNAL                        16

#ANY_LOCK_SIGNAL                        16

#V4_EVENT_MEM_SIZE                      32768

#ANY_EVENT_MEM_SIZE             32768

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.
