Even weird reject errors while on stratum
update cgminer, 2.10.4 , 2.10.5 and 2.11 all provide a lot of stratum tuning, your's is very outdated.
there will be some rejects or ocasional reconects, until ddos stopes. still most efficient pool for me.
I have checked out your miner's stratum stats. You have delivered 235 shares + 5 stales. That makes 2.1% stales rate.
If you are mining BTC, TRC or LTC at Coinotron it is better to use Stratum. Current stats of stales look like this:
Stratum Getwork
TRC 1.2% 2.5%
LTC 0.2% 1.6%
BTC 0.05% 1.3%
To be honest they are not much different than stats on previous server.
I was informed by koddos.com support that there were few small attacks on our new server.
That might cause temporary connection problems for some miners.
