Before the recent update i could load a pcap file of 6GB on wireshark but now after the update, the same file loads to a point it gives a message of "unspecified fatal error encountered, aborting" then wireshark shuts down. Could there be a reason?

What version were you running before the update, and what version were you running after the update? (The most recent update updated both the 3.2.x and 3.4.x versions.)

With version 3.4.4 I consumed 11 GB RAM for a 2047 MB PCAP file. Without a file loaded it uses under 100 MB of RAM.

There are two issues here:

  1. The fatal error, which is really weird, as that message appears to come from GLib, not from Wireshark itself, and would be reported only for certain fatal errors reported through GLib's g_log() interface in some weird circumstances, and looks really hard to produce;
  2. Large memory consumption for large files.

2 might be the cause of 1, but that's not clear.

In addition to the Wireshark versions before and after the update, we also need to know what version of what operating system is this on, and whether it's 32-bit or 64-bit.
