Subject: line scan camera with ADAravis driver skips frames

Hi everyone,
The camera that I am connecting to via GigE is a Basler Racer line scan camera (12288 x 1 px) model raL12288-8gm. When I run the camera with binning 1x1 and 8-bit pixel format at 1kHz (slowest frame rate), the driver keeps up until about 30K frames, at which point I start accumulating frame failures and underruns. With a higher frame rate, it happens almost immediately. 

I am using the latest areaDetector-master with ADAravis R1-3 and ADGenICam-master. I am running this IOC in a Docker using the host network which has MTU set to 9000. I made a slight adjustment to the ADAravis.cpp driver regarding setting the packet size to jumbo packets rather than determining optimum packet size, which was interfering with my network (lines 379-381 in ADAravis.cpp):
377     if (ARV_IS_GV_DEVICE(this->device)) {
378         // Automatically determine optimum packet size
379 //        arv_gv_device_auto_packet_size(ARV_GV_DEVICE(this->device));
380         // Uncomment this line to set jumbo packets
381         arv_gv_device_set_packet_size(ARV_GV_DEVICE(this->device), 9000);
382     }
I'm attaching snapshots of my camera features settings as well as my st.cmd and st.cmd.base files. Please let me know what other information you need. When I run this using the Basler pylonViewer software, I do not see these skipped frames.

Best,
Katie
