when keep following settings in config file , works fine.the settings follows :

resetonlogon=y resetonlogout=y resetondisconnect=y 

i want work following settings in config file.the settings follows:

resetonlogon=n resetonlogout=n resetondisconnect=n 

please kindly send me suggestions , settings run application without errors.

thanks , reguards, vishwesh raval.

your sequence numbers out of sync. output pasted says pretty clearly.

i suggest reading fix protocol. unfocused nature of question indicates don't know it. quickfix/n easier use , ask questions if spend time learning how protocol works. it's pretty simple protocol.
