## Symptoms

- /var/log/messages displays the following errors:  

`
[ERROR]: fileapp_parser_ftp_ctl_process_data_conn_tuple: current concurrent file_opqs is greater than limit(20). Will not create new file_opq`  
`
...`  
`
[ERROR]: fileapp_parser_execute_ctx: context 701 func failed
`

## Cause

File_opqs are created for each new data connection. They are counted for each control connection.  

Once customers are getting the following error:  

"\[ERROR\]: fileapp_parser_ftp_ctl_process_data_conn_tuple: current concurrent file_opqs is greater than limit(20). Will not create new file_opq"  

It means that a user opened from the same Control Connection more than 20 concurrent Data connections.  
Check Point added it as a safety mechanism to prevent this behavior as an attack vector.
