Dear list,
When I run CT tests multiple times I encounter a bug.

========
erl -pa apps/*/ebin -pa deps/*/ebin \
    -name [email protected] \
    +K true \
    +P 5000000 \
    +Q 1000000 \
    -env ERL_FULLSWEEP_AFTER 10 \
    -config myapp \
    -mnesia schema_location ram \
    -noshell \
    -eval 'ct_run:run_test([{dir, "apps/myapp/test"}, {logdir,
"apps/myapp/logs"}]).' \
    -s erlang halt
=========


Running this the first 2/3 times will give:


=========
Common Test starting (cwd is /Users/roberto/workspace/myapp)


Common Test: Running make in test directories...

CWD set to:
"/Users/roberto/workspace/myapp/apps/myapp/logs/[email protected]_16.25.39
"

TEST INFO: 1 test(s), 1 case(s) in 1 suite(s)

Testing apps.myapp: Starting test, 1 test cases
Testing apps.myapp: TEST COMPLETE, 1 ok, 0 failed of 1 test cases
=========


After the 3rd time or so (this happens randomly), I get:


=========
$ ./tests

Common Test starting (cwd is /Users/roberto/workspace/myapp)


=ERROR REPORT==== 22-Apr-2015::16:26:00 ===
Error in process <0.42.0> on node '[email protected]' with exit value:

","0","0","1","2015-04-22_16","25","26"]},[{ct_logs,'-sort_ct_runs/1-fun-0-',2,[{file,"ct_logs.erl"},{line,1912}]},{lists,sort,2,[{file,"lists.erl"},{line,967}]},{ct_logs,make_all_suites_index,1,[{file,"ct_logs...
=========


If I delete the directory where the CT logs are stored I can re-run the
command, without issues.

Any ideas?

Best,
r.
