FTP and rtp-base session end reason resources-unavailable after upgrade PANOS from 8.1.7 to 9.0.5

[Champion]

Hi, 

We have recently upgraded our 5250 from PANOS 8.1.7 to 9.0.5.

And FTP started to have slowed down.

After checking traffic log, there were some FTP session ends with resources-unavailable.

It's about every 10 sessions will have one with resources-unavailable.

Also, there were some rtp-base sessions have the same session end reason.

It's impacting the performance of FTP.

Is it a bug of PANOS 9.0.5?
