Teamcity 100% CPU usage all the time!
We've been seeing 100% CPU usage in the teamcity server all the time, goes up and down a bit but it's always hitting 100% every 10s. Uploaded a memory snapshot from diagnostics in the portal - memoryDump-2018-01-20_15.31.02.hprof.gz

Ping
same issue here !!!!!
Sorry for not replying in time. Is the issue still actual?
If so, could you please investigate it per our notes? Basically, make sure it's the main TeamCity server process which is using CPU and if so, take a set of the server thread dumps and send us an archive of the entire TeamCity server logs directory (most importantly, all the teamcity-server.log* and threadDumps- directories).
