Hello,  
after update my plot function hangs. Simply typing  
using Plots  
plot(rand(10))  
the REPL hangs and I can only recover with an explicitely kill of julia.

I have done an Pkg.update(), there has been an update of one Package, I don’t know what and I don’t know which package (maybe GR). Simply looking for the dates in .julia/Packages doesn’t resolve this problem.  
Is there any log where I can look what has happened?  
plot worked 12 hours before.

Can you run `] build` and see if that fixes things?

I don’t know if this is relevant, but in ~/.julia/packages/Libtask/GQPaW/deps/usr/lib I only find libtask\_v1\_0.so libtask\_v1\_1.so libtask\_v1\_2.so libtask\_v1\_3.so  
Is libtask\_v1.4.so missing?

Meanwhile my problem is (partially ?) solved. There has been a zombie, where no zombie should have been there: With ps -xa I got

4248 ? S 0:00 /home/ad08/.julia/packages/GR/yMV3y/src/…/deps/gr/bin/gksqt -session 10d8d4d463000158738063300000040530036\_1588720716\_353325

After “kill 4248” my julia works. But why has 4248 been left from former calls to julia?
