Cannot obtain a lock on data directory



I mined some Florincoin.

I get a lot of

2018-05-04 17:25:04 Error: Cannot obtain a lock on data directory /home/crypto2/.florincoin/. Florincoin Core is probably already running.
2018-05-04 17:25:04 Shutdown: In progress…
2018-05-04 17:25:04 StopNode()
2018-05-04 17:25:04 Shutdown: done

Any idea?

Also i can send some payments, i see the money leaving from the wallet, then i don’t see it in the block chain as if i lost the money.

I tried both SEND and SENDMANY.

I tried to reboot, to delete .lock file, to chmod .lock file, nothing. Any idea?

The sad thing is that it worked, i managed to send 50 blocks worth of value last week, this week i don’t know what happened.

Thank you.
