IOError while running under teamcity #358

I'm not completely sure that this is a parallel_tests issue, but I think it may be. While running under teamcity, I think one of the processes is getting an IOError while writing it's logs.

The main process is doing:

teamcity  5839  5838  2 16:31 ?        00:00:01 ruby /mnt/teamcity/TeamCity.9.0/buildAgent/work/master/vendor/bundle/ruby/2.1.0/bin/parallel_test features --type cucumber --test-options --profile parallel_ci --expand --format Teamcity::Cucumber::Formatter --serialize-stdout -n 8

a subprocess is doing:

teamcity  5844  5839  0 16:31 ?        00:00:00 sh -c TEST_ENV_NUMBER=;export TEST_ENV_NUMBER;PARALLEL_TEST_GROUPS=8;export PARALLEL_TEST_GROUPS;bundle exec cucumber  --format ParallelTests::Gherkin::RuntimeLogger --out tmp/parallel_runtime_cucumber.log --profile parallel_ci --expand --format Teamcity::Cucumber::Formatter [features]

and then frequently I get the following error in teamcity:
