Wireshark · Wireshark-bugs: [Wireshark-bugs] [Bug 8460] crash while computing "io graph" for sctp/m3ua/isup traffic

[bugzilla-daemon@xxxxxxxxxxxxx]

Comment # 2 on bug 8460 from Cristian Constantin

it works with resolutions of 0.1s, 1s but it limits the graph to the first 100k
entries.

when I set the resolution to 10s it stalls (deadlock?) after processing 7% of
the traffic. here is how the stack trace for both threads looks like:
