RAK7249 How durable is the flash storage for the log files?

On the RAK7249 I am seeing new logfile entries every 30 seconds:
They are approximately 24 lines long each formatted like this:

##### 2021-08-22 21:37:31 UTC #####
Sun Aug 22 21:37:31 2021 user.notice lora_pkt_fwd[22068]: ### [UPSTREAM] ###
Sun Aug 22 21:37:31 2021 user.notice lora_pkt_fwd[22068]: # RF packets received by concentrator: 5
Sun Aug 22 21:37:31 2021 user.notice lora_pkt_fwd[22068]: # CRC_OK: 60.00, CRC_FAIL: 40.00, NO_CRC: 0.00
Sun Aug 22 21:37:31 2021 user.notice lora_pkt_fwd[22068]: # RF packets forwarded: 3 (70 bytes)

and occasional messages of “daemon.err uhttpd[1773]: Device “apcli0” does not exist.
Sun Aug 22 21:44:06 2021 daemon.err uhttpd[1773]: connect ERROR: Connection refused”

My question is this concerning? Will those log writes wear out the flash storage over time?
Or is the RAK7249 logging to RAM only?
Should I reduce “lora_pkt_fwd” log verbosity from NOTICE to WARNING?
