It is actually the master(central) that determines the connection interval, so increasing the maximum connection interval on the slave(peripheral) doesn't necessarily help. You can try to increase the minimum connection interval as well, then the master will either use a connection interval between min and max, or reject the slave.

Edit 07.05.2015: When the SoftDevice is enabled you should use sd_flash_page_erase() and sd_flash_write() functions. Please see Section 7 in the S110 SoftDevice Specification 2.0 for more information. If the flash operation is succesful you will get a NRF_EVT_FLASH_OPERATION_SUCCESS event in sys_evt_dispatch(). I recommend you to have a flag that is set you do a flash operation, and is unset when you get NRF_EVT_FLASH_OPERATION_SUCCESS. Check the flag before you do a flash operation.

We also have a module for handling flash operations, Pstorage.
