I'm using version 40000 of bitcoind and yesterday it stopped receiving new confirmations. Here is the getinfo for it.
"version" : 40000,
"balance" : x,
"blocks" : 225454,
"connections" : 8,
"proxy" : "",
"generate" : false,
"genproclimit" : -1,
"difficulty" : 4367876.00084220,
"hashespersec" : 0,
"testnet" : false,
"keypoololdest" : 1362824413,
"keypoolsize" : 101,
"paytxfee" : 0.00000000,
"errors" : "URGENT: upgrade required, see http://bitcoin.org/dos for details"
My blkindex.dat is currently 7.89GB (split over 5 files) and database log c. 12GB.
What should I do to fix this? I see that it's recommended to upgrade due to a DOS vulnerability but unless I am sure that this is the cause of the problem I don't want to go to the trouble of changing the setup.
