Hi, i,ve managed to create some bags starting from some carmen log file. Now i'm trying to use those bags with for gmapping but while rosbag play doesn't show any error, gmapping get stuck at:

update frame 0
update ld=0 ad=0
Laser Pose= 0 0 0
m_count 0
Registering First Scan

so when i try to get the map file using "rosrun map_server map_saver" only a partial map file is given.

While doing this procedure with the bag given in the gmapping from logged data tutorial nothing get wrong.

one of the bags i'm trying to use is this:

Is there a way to check if the bag is suitable for what i'm doing ? what can be the problem ?

Try playing your bag as follows......

$rosparam set use_sim_time true

$rosrun tf static_transform_publisher 0 0 0 0 0 0 base_link laser 100

$rosbag play --clock <your-ros-bag.bag>

Hope it works.
