It's known that capturing a memory snapshot pauses application threads, and to reduce the pause you may capture HPROF format snapshots instead:

However, the times you are talking about (half an hour) are extremely high, and it looks like something went wrong.
Could you please provide the profiler agent log file ~/.yjp/log/<session name>-<pid>.log

Version 2013 is unsupported. If the problem is still reproducible with version 2014 could you please send the new log file.

Please also note you used the attach mode. Please start the profiled application with the agent instead, as this may increase snapshot capture speed.
