Hi,

I was playing one of the contests from Opentrains today, but system was very unreliable:

• I saw a lot of times result "Check failed"

• When I sent the same solution, but different languages, I got a few times "Check failed" and once "AC"

• The same solution on different attempts get PE18, PE34, PE36 etc.

• When I was trying to submit solution, I got a lot of times "Disk write error (disk full?)" message, and my solution wasn't submitted.

I believe there are problems with Opentrains. Can someone who has access check and fix it?

Thanks!
