WebGUI: Diagnostics > Packet Capture will try to display any size of pcap file.
100%
Description
The diag_packet_capture.php p[age will try to display any size of pcap when the capture is stopped regardless of how large it is.
This can result it either long load times and an unmanageably large page or at larger sizes it exhausts the available php memory for a single page:
Crash report begins.

However it is still possible to download the capture when this happens.
It would be nice to see it show just a message explaining why it's not showing the capture. Or maybe a new detail level of 'None' so you have to deliberately choose 'Normal' to attempt to display it. That could apply to any capture over, for example, 5000 packets.

Either or both of those should be fairly simple to do..

Even when downloading a too large capture it will fail..... (it just has to be large enough).

Invoked a lot of traffic while running pcap with unlimited packet count. Got message when stopped pcap in 30 min:
Packet capture file is too large to display in the GUI.
Download the file, or view it in the console or ssh shell.
pcap file 1.8G was available for downloading
Looks good.

On 2.4.5.a.20190201.0810, tested with an iperf3 traffic stream running over WAN with a simultaneous packet capture on the same interface for about 5 minutes at about 700-800 Mbps. When the packet capture was stopped,

appeared in the Packets Captured box. Clicked Download Capture button and the resulting multi-gigabyte capture file downloaded without issue.
