Unfortunately the 5.18.0 version of IPC::Open3 does not output the value of $! in case of an exec failure (see https://metacpan.org/source/RJBS/perl-5.18.0/ext/IPC-Open3/lib/IPC/Open3.pm#L277 ). I've seen similar errors where the $! value was "Argument list too long". This usually happens if PERL5LIB is too long and exceeds the environment's maximum length. However, on current Unix systems this is typically more than 100kB, and PERL5LIB in the problematic report is far from this limit. > > Could you please see if this is repeatable?

I do this (sort of) in my smoker wrapper: if a test report matches m{Could not execute .* open3: exec of .* failed: Argument list too long at .*TAP/Parser/Iterator/Process.pm} then it will not be sent to metabase.
