Description:
Data nodes died if to create many datafiles for table space.

How to repeat:
1. Create a new simple config.ini where added InitialNoOfOpenFiles=20 (or use from
attached file)
2. Start cluster.
3. Run script (from attached file) as it described below:
./sqe.pl -q ats1.txt -p 127.0.0.1:3306:root
4. Wait while the script will stop and look into error and trace log files

Suggested fix:
Seems error is correct in error_log but why nodes die?

Hi,

Please do it as this instead.

- Have ndbfs send back a FSOPENREF with new error code instead.
