Asa ftp uploadproblem

Question

hi
I have a problemm i have a asa 5510 box running 7.2 ios. now asa has inspect configured for FTP on 21. Now the problem is that whether in active mode or pasv mode everything wrks fine like i can dwnload and brws the directory. now when i try to upload any file it starts and after transfering some bytes it stops n times out after some time.i tried many diff ftp servers and applying acl for matching ftp traffic and everything wrks fine (acl matches ftp traffic) problem persists only for ftp uploads (both activ n pasv)..

Not sure if this is the issue but you might do a sho asp drop and check to see if the out-of-order packet buffer count is increasing (need to do the sho asp drop several times). If it is increasing, you can increase the number of buffers on your ASA by increasing the queue-limit. Here is an example..
hostname(config)# tcp-map tmap
hostname(config-tcp-map)# queue-limit 60
hostname(config)# class-map cmap
hostname(config-cmap)# match port tcp eq telnet
hostname(config)# policy-map pmap
hostname(config-pmap)# class cmap
hostname(config-pmap)# set connection advanced-options tmap
hostname(config)# service-policy pmap global
hostname(config)#

This may or may not be your problem, but it is worth a shot.
