what version are you using? you are using tcp::collect in irule, aren't you?

 

anyway, i think you had better open a support case.

Hi nitass,

 

Sorry for disappear such as long time. My version is 12.1.2. Yes,I did using a TCP::collect in irule. After I did opened case with support, Support claims that this issue triggers by extra bytes from client's GET requests when using TCP::collect and LB::detach on my irules and support suggests to revise my irule logic and avoid using these two commands.

 

Regards,
