error closing

edit

I'm trying to record playback of a tool using rosbag record. However, when I terminate the record command with CTRL+C (as described in section 1.1.1 here), I get the following error:

^Cterminate called after throwing an instance of 'rosbag::BagIOException'
what():  Error closing file: file_pc_2015-10-07-16-19-20.bag.active

I'm not quite sure what to make of it. My original command is:

rosbag record <topic1> <topic2> <topic3> -o file_pc.bag

and it produces the following response:

[ INFO] [1444249652.685549431]: Subscribing to <topic1>
[ INFO] [1444249652.689816172]: Subscribing to <topic2>
[ INFO] [1444249652.693818845]: Subscribing to <topic3>
[ INFO] [1444249652.699418268]: Recording to file_pc_2015-10-07-16-27-32.bag.

Thank you in advance for the help!
