[tarantool-patches] Re: [PATCH v1] test: enable parallel testing for vinyl suite

[Alexander Turenko]

I have enabled core files: ulimit -c unlimited.

Then I run:

for i in $(seq 1 100); do ./test-run.py -j 30 --long vinyl/ || break; done

And observed the following crash:

[020] [Instance "low_quota" killed by signal: 11 (SIGSEGV)]

Program terminated with signal SIGSEGV, Segmentation fault.

2.2.0-179-ga00169714.

Also I found a bunch of open issues re vinyl in parallel mode, added to
#4158. Please, resolve them first.

WBR, Alexander Turenko.
