When FTP is used with bigproto, the PVA client-side current connections stat does not decrease after connections are closed.
An incorrect stat for client-side current connections will be reported for 'tmsh show sys pva-traffic global' and 'tmctl pva_stat'. Example: config # tmsh show sys pva-traffic global ------------------------------------------------- Sys::PVA ------------------------------------------------- PVA Traffic ClientSide ServerSide Bits In 23.6K 219.7K Bits Out 219.7K 23.6K Packets In 40 335 Packets Out 335 40 Current Connections 295 0 <----- Maximum Connections 296 8 Total Connections 335 40 Miscellaneous Cur PVA Assist Conns 0 Tot PVA Assist Conns 335 HW Syncookies Generated 0 HW Syncookies Detected 0 config # tmsh show sys conn all-properties Really display 1000 connections? (y/n) y Sys::Connections Total records returned: 0 <--------- No connections; this is the correct state.
-- Use an FTP virtual server. -- End user clients connect to the virtual server.
This issue does not occur when 'inherit parent profile' is enabled on the FTP profile used by the virtual server.
The client-side current connections stat is decreased when connections are closed. 'tmsh show sys pva-traffic global' and 'tmctl pva_stat' now show accurate data.
