This issue is generated when the server tries to write the data from the memory to the hard disk. It may be caused by the hardware directly. Since the default "Memory Diff" is 3600 blocks, bottom + top, then it needs to handle 7200 blocks.

Check the log here, 21633285 - 21626085 =7200, looks like some errors in the process(related to the physical machine).

The suggestion for this issue is to reduce the "Memory Diff" and resync the blockchain if this is generated. Change the blockchain settings in the conf file, for example, change to 500 as https://github.com/virtualeconomy/v-systems/blob/757273c368bce861803c45c9cdba8059a964e2ec/vsys-mainnet.conf#L43-L44

Thanks, will have a try.
